Asked by ninaaaa

Which equation represents the axis of symmetry of the function y=-2x^2+4x-6

A y=1
B x=1
C x=3
D x=-3

Is the answer C?

Answers

Answered by Steve
the axis is x = -b/2a = -4/-4 = 1

So, B

-2x^2 + 4x - 6 = -2(x-1)^2 - 4

You could easily see that x=3 is wrong, by checking f(x) at values equally spaced from it, as f(2) and f(4). If x=3 is the axis of symmetry, they should be the same. But,

f(2) = -6
f(4) = -22
