Question

What is the maximum or minimum value of the function? What is the range?

y = –2x2 + 32x –12

Answer 1

Find the vertex(h,k)--------->Write the equation to the form: a(x-h)^2+k

Answer 2

how do i do that

Answer 3

how do i convert standard form to vertex form

Answer 4

h=-b/2a after you get h value you can plug it in the equation to find value of k, or you can find k=c-(b^2/4a)
a<0 so you will have parabola open down-----> vertex=maximum

Answer 5

thanks

Answer 6

You are welcome!

Answer 7

wait whats the range then

Answer 8

The range (negative infinity, k)

Answer 9

ok thanks again

Answer 10
