Write y= -4x^2+8x-1 in vertex form.?

y= -4x^2+8x-1\ny = -(4x^2-8x+1)\ny = -[(2x-2)^2 - 4 + 1]\ny = -[(2x-2)^2 - 3]\ny = 3 - (2x-2)^2\n\nSo the vertex is (1,3) and it is a maximum point.

y = 3x^2 + 12x - 7\nWhat do the directions say?

Slope intercept form:  y=mx+b where m= the slope and b= the y-intercept.\n\ny=2x-4

-4y^+8y+3y^2-6\n-4y(y^2-2)+3(y^2-2)\n(-4y+3)(y^2-2)\n\ndoes that make sense?

y=x^2+10x+8\ny=(x+5)^2 - 17\n\nVertex form: (5,-17)

Just add and substract terms in both sides.\n\nSince \ny-x^2+8x\nis equal to 7, \nyou can add x^2 and substract 8x to both sides.\n(y-x^2+8x) +x^2-8x = y\n7 +x^2-8x = x^2-8x+7\n\nso y=x^2-8x+7\n\nby the way, if you factorize in terms of x then you'd get\ny=(x-1)(x-7)

y = 0.5x-4 \n\nor similarly\n\nx= 2y +8

You are given the quadratic function\ny = x² - 8x + 22\n\nTo find the vertex, change the given equation into the form\ny = a(x - h)² + k\n\nWhere \na = is a constant\n(h,k) is the vertex\n\nThus,\ny = x² - 8x + 22\n\nWe complete the square, by squaring the half of the coefficient of x (which is -8, the half of -8 is -4, and the square of -4 is 16.)  Thus,\ny = x² - 8x + 16 + 6\n\nNow, we can factor\ny = (x - 4)² + 6\n\nTherefore, the vertex is\n(4,6)\n\n^_^

Quadratic Functions have the form y = ax^2 + bx + c\n\nThe vertex will always have x = -b/(2a). You can calculate this number and plug it into your equation to solve for y. If a is positive, the graph will go up in both directions from the vertex. if a is negative it will go down. You can pick some x value different from the vertex to help you plot other points to allow a symmetric parabola graph.\n\nGood Luck!

Use factoring.\nx2-2x-8=0\n(x-4)(x+2)=0\nso\nx-4=0 and x+2=0\nsolve\nx=4 and x=-2

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

x-4y+4=12\n\nyou want to get it in y= mx + b form \n\nso switch the 4y and the 12 \n\nx + 4 -12 = 4y\nx - 8 = 4y\n\nnow divide by 4\n\n(1/4)x -2 = y\n\nso the slope is 1/4 and it crosses the y axis at -2\n\nsome points are \n(0, -2)\n(-4, -3)\n(-8, -4)\n(4, -1)\n(8, 0)\n(12, 1)\n\nhope this helped\nbest of luck
