y = 1
y = 1

x = 1
x = 1

x = 3
x = 3

x = –3

Answer 3

The axis of symmetry of the function y = -2x^2 + 4x - 6 can be found using the formula x = -b/(2a). Here, a = -2 and b = 4.

x = -4/(2*(-2))
x = -4/(-4)
x = 1

Therefore, the equation representing the axis of symmetry is:

x = 1

Correct Answer: x = 1
