Question

PLEASE HELP!!!

Given the function f(x)=(x+1)(x-3)

a) What are the x-intercepts?
b)What is the axis of symmetry?
c)What is the vertex?

Answer 1

a) (-1,0) and (3,0)

b) x=1

c) (1, -4)

Explanation:

As you can see in the graph below, the x intercepts of this graph are at (-1,0) and (3,0), the axis of symmetry is x=1, and the vertex is at (1,-4). Hope this helps!
