Question

The polynomial f(x) has zeros at x=6−3i, 6+3i, and −1.

Which graph could be the graph of f(x)?

Answer 1

It is the second graph.

Explanation:

One zero is x = -1 so the graph will be curved (as it has degree 3) and will pass through the x axis at x = -1 and only at -1 because the other 2 zeroes are complex numbers.
