whats the inverse of Y=1/2X-3/2?

switch x and y\nx=1/2y-3/2\n1/2y=x+3/2\ny=2x+3

y=5\nx=-2/3\n\nSame method as the other one.

You can do it by hand or with a calculator. Either way, it would look like this:\n\n2x + y = 3 \n(move the 2x to the right side of the equation, so only y is on the left side)\ny = 3 - 2x\n\nNow put 1, 2, 3, etc. in for x, and see what y equals:\n\nwhen x=1, y=1\nwhen x=2, y=(-1)\nwhen x=3, y=(-3)\nand so on.....\n\nNow put these values into a table:\n\nx --- y\n1 --- 1\n2 --- (-1)\n3 --- (-3)

switch the y and x\n\nx = 2y - 3\n\nThen solve for y\n\nx + 3 = 2y\n\n(x+3)/2 = y\n\nnow you have the inverse.

it's (xy) / 2 - 1 * 3 + 1 - 2 which is (3xy) / 2 - 2 because remember the order of operations

(y--1)/(-2--1)=(x-1)/(2-1)\n=(y+1)/(-2+1)=(x-1)/(1)\n=>y+1=-1(x-1)\ny+1=-x+1\ny=-x is the required equation

you would take the 2x-4y=3 and solve for a variable, such as x=(3-4y)/3   you now have what x equals and you sub that into the other equation so you now have 2[(3-4y)/3]-3y=0 and you should be able to solve that equation

To differentiate y= 2/x\n\nFirstly you get rid of the fraction by taking X to the top(this will make its power negative) giving:\n\ny=2x^-1\n\nFrom here its just a simple case of carrying out the differentiation:\n\ndy/dx = -2X^-2 or dy/dx = -2/X^2

(y(1)-y(2))/(x(1)-x(2)) =\n(3-(-2))/(3-8) =\n(5)/(-5) =\n-1

y = 2x is the function then the inverse is x = 2y (switch x and y) there fore F(x) ^-1 is inverse

y = -2x + 8\n\nsolve it yourself

(x^2-x^(3/2))/2x^2 = 1/2-sqrt(x)/2\n        =1/2(1-x^(-1/2))\n\nd(1/2(1-x^(-1/2)))/dx\n=1/2(-(-1/2x^(-3/2))\n= 1/4x^(-3/2)\n\ni hope that this helps

x=0,2,3,4 and y=1,-1,0,3

y = 3/(1 - x)²\n\n1, (1 - x)² ≥ 0 for all x and therefore 3/(1 - x)² ≥ 0 for all x\n\n2. 3/(1 - x)² is undefined when x = 0. Therefore 3/(1 - x)² (ie y) → +∞ when x → 1 from the left of 1 and when x → 1 from the right of 1\n\n3. As x → ±∞, 3/(1 - x)² (ie y) → 0\n\n4. Plot a few other points and Bob's your uncle!!
