Answer:
Here's what I get
Step-by-step explanation:
If the function has three zeros with one relative maximum and one relative minimum, it could be a cubic equation.
If it has a factor of x - 4, the graph crosses the x-axis at (4,0).
Your graph might look like the one below.
It has three zeros, one of which is at x = 4, and a local maximum and minimum.
It's basicly adding and subtracting hope this helps
