Question

PLEASE HELP!!! POP QUIZ NEXT CLASS!!!!

Jamie graphed the quadratic function Y=-2x^2 - 12x+3. The equation of the line of symmetry of the functions is x=-3. What is the vertex of the function?

Answer 1

convert it to vertex form

a(x - h)^2 - k

Answer 2

How do u do that, like i dont understand the question ,nor how to covert it.

Answer 3

so like would it be (-3,21)

Answer 4

well i answered your question but lost the system

Answer 5

the x coordinate would be -3

vertex form is a(x -h )^2 - k kis y coordiante of vertex

Answer 6

Y=-2x^2 - 12x+ 3
= -2(x^2 + 6x - 1.5)

Answer 7

thanks! lol
