Question

What are the zeros of f(x)=2x^3+3x^2-9x?

Answer 1

x = -3, x= 0, and x = 1.5

Explanation:

The zeros of a function f(x) refers to the x-values for which f(x) = 0.

We simply graph the function and determine the points where the graph crosses the x-axis. Thus, we shall be solving the problem graphically;

From the attachment below, the graph of f(x) crosses the x-axis at;

x = -3, x= 0, and x = 1.5
