Answer:

x = 2

Explanation:

f(x) = -2x² + 8x - 9

Comparing this function with f(x) = ax² + bx + c

a = -2, b = 8, c = -9

The axis of symmetry is given by the formula:

x = -b/2a

Substitute a = -2 and b = 8 into the formula:

[tex]\begin{gathered} x=\frac{-8}{2(-2)} \\ \\ x=\frac{-8}{-4} \\ \\ x=2 \end{gathered}[/tex]

x = 2
