Question

Find the y-intercept and the axis of symmetry of:
f(x) = ax^2 + 8ax - 5

Answer 1

y-intercept (0,-5) and AOS x = -4

Explanation:

To find the y-int make x = 0 so f(0) = -5

The axis of symmetry (AOS) can be found by the equation x = -b/2a

So AOS = -8a / 2a, so AOS = -4 since b=8a and a = a
