Question

The degree of the polynomial function f(x) is 3.

The roots of the equation f(x)=0 are −1 , 0, and 4.

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

Answer 1

A

Explanation:

Given the roots are x = - 1, x = 0 and x = 4

Consider the graph where f(x) intersects with the x- axis at these points

The only graph is A
