What are some uses of the graph y=1/x ?

This graph helps us to show what happens when a quantity y is inversely proportional to another quantity x.\n\nAgain, it shows us that a computer algorithm implementing y=(1/x) for the order of efficiency of the algorithm..

y = -1/2 sin·­­­¹ pi x\nTo graph this, it is easier to rearrange to make x the subject, then turn the graph paper on its side and plot x as a function of y, just remember that y is now positive going left and x is positive going up.\n-2y = sin·­­­¹ pi x\nsin (-2y) = pi x\n1/pi sin (-2y) = x\n\nnow sin (-2y) = sin 2y   (check your trig properties)\n\nso we want to graph\nx = 1/pi sin 2y\n\nnow for the graph  y = a sin bx\nthe amplitude is a and the period is 2pi/b\nso the amplitude is 1/pi\nthe period is 2\n\nPlot your sin function along the y axis. Then turn the paper the right way up. Remember that to be a function, it can only have one value of y for each value of x, you only want a single half S shape, going from y = -.5 to .5, this way the graphs remains a 1 to 1 function.

The above answer is basically correct.  Plug in a few more values, such as (21,1543.5), (22,1694), and so on for a few more values of the graph.

It allows you to see the relationship between the variables better than you could in a chart.  You can also find the mathematical relationship by calculating the slope of the graph and determining the equation of the line.

You only need two points to determine a line.\nYou should use three just to make sure you don't make a mistake.\nPick two values of x and find the corresponding values for y.\nThis one is pretty simple.\nLet x = 0, then y = 0 (since y = x)\nLet x = 1, then y = 1\nLet x = -3, then y = -3.\nPlot these points on the graph and connect them with a straight line.

To graph functions, first get a piece of graph paper or you can free hand the X-Y axis and plot the points between -5 and 5 on both axis.\n\n1) h(x) = 2/x  domain of x (-1, 0, 1, 2)\n\nFind the coordinate pairs for each member of the domain.\nh(-1) = 2/-1  -->  (-1, -2)\nh(0) = 2/0  -->  undefined so no point on the graph\nh(1) = 2/1  -->  (1,2)\nh(2) = 2/2  -->  (2,1)\n\nThe graph will be the three points above.  It is not a line since the domain is limited to the integers listed.\n\n\n2) f(x) = x-1  domain is x/x is a real numbers (which excludes x=0 from the domain, but includes all other real numbers)\n\nSince the equation is in slope-intercept form, i.e.  y = mx + b\nthe slope of the line is m=1 and the intercept on the y-axis is b=-1\n\nYou can draw the line that way, or determine two points on the line like this:\nf(-1) = -1 - 1  -->  (-1,-2)\nf(1) = 1 - 1  -->  (1, 0)\n\nSince the domain is the real numbers except 0, a solid line is drawn to extend beyond both points.  Either way you draw the line, make an open point (ie. a circle) on the line where x=0.  Don't draw the line through the open point.  The line is terminated with arrows to indicate that it extend to infinity in both directions

((1/x) + (1/y)) / ((1/x) - (1/y))\n\n((y + x)/xy) / ((y - x)/xy)\n\n((y + x)/xy) * ((xy)/(y - x))\n\n(xy(y + x))/(xy(y - x))\n\n(y + x)/(y - x) = (x + y)/(-x + y) = (x + y)/(-(x - y)) = -(x + y)/(x - y)

There are infinitely many answers of the form\n(x,y) where y = (18 - 21x)/20 and x is any real number.\nIf you're looking for a graph, this is a straight line with slope -21/20 and y-intercept 9/10.

in a graph, the x coordinate defines distance right or left.\n\nthe y coordinate defines distance up or down.

Consider the function f as mapping the points x of a set X to the points y of a set Y. Draw a horizontal line (the x axis) so that each point on the line represents an element of the set X. Draw a perpendicular line (the y axis) to intersect the x axis at the null point or zero. Each point on the y axis represents an element of the set Y. \n\nFor each x in X calculate the value of y= f(x) in Y. This gives a pair of co-ordinates (x,y). (Depending on the function, you may have more than on value of y for each x eg the function f(x)=square root of x will give + and - values.)\n\nFor any x on the x axis draw a line parallel to the y axis to intersect the x axis at x. Draw another line to intersect the y axis at the point y=f(x) and parallel to the x axis. Where these lines intersect is a point on your graph. The complete graph consists of all such points.\n\nWhere the set X is infinite (eg the set of real numbers) you cannot calculate the value of f(x) individually for every x but by calculating the values for a series of points at suitable intervals you will see a pattern emerging to the graph and you will be able to fill in the gaps by joining the (x,y) points, hopefully with a smooth and continuous line.

The graph of sin x goes up to 1 when x = pi/2. When you graph y = sin (2x), it shrinks the x-values by half - so it will be 1 when x = pi/4.

Thinner simple work its cause the 3 is greater than the one other than drwing the grph there is really no work. And if u need the graph then just make an X Y table using values -3 to 3 then solve for y and gragh them

IF you mean like an ordered pair it is a point on a graph.  An example is:  (x,y)  so you can have (3,5)  or (-7,-88)  Otherwise I'm not sure what you're talking about.

Draw the graph of y = x^3\nThe (x-1) part shifts the graph to the right by 1.\nThe +4 part shifts the graph up by 4.\n(0,0) lies on y = x^3\n(1,4) lies on y = (x-1)^3 + 4\nNote that the x-coordinate increased by 1 and the y-coordinate increased by 4.
