Question

Identify the x-intercepts, vertex, and axis of symmetry of the graph of

f(x) = 2(x+4) (x+8).

What are the x-intercepts
What is the vertex
The axis of symmetry is x = what

Answer 1

f(x) = 2(x + 4)(x + 8)

x-intercepts: x = -8, -4

vertex: (-6, f(-6)) = (-6, -8)

axis of symmetry: x = -6
