Question

The graph of y = f(x) is shown below. What are all of the real solutions of f(x) = 0?

Answer 1

Answer:

(-8, 0), (0,0) and (7, 0)

Step-by-step explanation:

When f(x) = 0 the curve of f(x) intercept x-axis, that is, y = 0. This points are called roots or zeros of the polynomial.

From the picture, we can see that f(x) = 0 at points (-8, 0), (0,0) and (7, 0)
