Question

Find the equation of the axis of symmetry for this function.

Answer 1

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 = - $\frac{b}{2a}$

f(x) = 4x² - 8x + 5 ← is in standard form

with a = 4 and b = - 8 , then equation of axis of symmetry is

x = - $\frac{-8}{8}$ = 1
