Question

find the vertex, the line of symmetry, the maximum or minimum value of the quadratic function.. f(x)=-2X^2+2X+7

Answer 1

x=1/2

Answer 2

i have to put it in as a fraction. like 1/2

Answer 3

(1/2,15/2)

Answer 4

yea i got 1/2 now then is it 15/2?

Answer 5

wud the equation be x=15/2?

Answer 6

x=1/2 is the line of symmetry and the vertex is at (1/2,15/2)

Answer 7

yea i got those answers would my equation be correct?

Answer 8

why would you need x=15/2?

Answer 9

15/2 is the y-value that corresponds to the maximum.

Answer 10

it is asking for the equation of the line of symmetry

Answer 11

it would be x=1/2
