Which of the following statements are true of the graph of the function f(x)=(x+5)(x-3)

The graph has a relative maximum
The graph has a relative minimum
The graph has an x-intercept at (5,0)
The graph has an x-intercept at (3,0)
The graph has a y-intercept at (0,-15)
The axis of symmetry is x=-2

The following statements are true of the graph of the function f(x)=(x+5)(x-3):

- The graph has a relative minimum.
- The graph has x-intercepts at (5,0) and (3,0).
- The graph has a y-intercept at (0,-15).
- The axis of symmetry is x=-1.

The axis of symmetry is x=-1 is not an answer

Apologies for the error. The correct statement is:

- The axis of symmetry is x=-1.
