Question

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

Answer 1

x = -4, 4

Explanation:

Given graph in the attachment represents the function y = f(x)

Real solutions of the function means all the points where the curve of the graph either touches or crosses the x-axis.

Since, graph of the function touches and crosses at x = -4 and x = 4

Therefore, all real solutions of the function are x = -4 and x = 4
