Question

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

Answer 1

The answers are 0,-1,-3

Answer 2

0, -1, -3

Explanation:

f(x) = y = height of the line plotted

if you treat the x axis as the "ground" or "floor"....you're looking for the point when the graph "hits" the "floor", meaning zero height.
