Answer:
x = 1
Step-by-step explanation:
Given a parabola in standard form
f(x) = ax² + bx + c ( a ≠ 0 )
Then the equation of the axis of symmetry is
x = - [tex]\frac{b}{2a}[/tex]
f(x) = 4x² - 8x + 5 ← is in standard form
with a = 4 and b = - 8 , then equation of axis of symmetry is
x = - [tex]\frac{-8}{8}[/tex] = 1
