7. Complete the square to rewrite each quadratic function in vertex form, describe the transformation, and then graph the function. A sample is provided for your reference. Sample: a) f (x) =x - 4x +6 b) 1(x ) =2x 16x + 7 y = 3x2 -12x+7 y =3(x - 4x) +7 y =3(x2 -4x+4)+7-12 y =3(x-2)? -5 8. Use x= - to find the vertex of the function in question 7a and 7b. What do you notice? 9. Find the equation of a quadratic function of the form f (x) = a(x-h) Jk with the given Information: a) passes through (2, -13) and has vertex (-1, 5) b)
