Question

PLEASE HELP MEEEE!!!!

What is the equation for the line of symmetry for the graph of the functiony=-4x^2+6x-8?

A.
x=-3/4
B.
x=-1/2
C.
x=3/4
D.
x=1/2

Answer 1

the axis of symmetry of y=ax²+bx+c is -b/(2a)

given

y=-4x²+6x-8
a=-4
b=6

axis of symmetry is -6/(2*-4)=-6/-8=6/8=3/4

answer is C

Answer 2
