Answer:
x = 1, 4
Step-by-step explanation:
We assume the graph is of the relation y = f(x). The desired values of x are those that correspond to points where the y-value is -2.
Reading the graph
We are only interested in the x-coordinates of points that lie on the horizontal line where y = -2. Those points are (1, -2) and (4, -2).
The values of x such that f(x) = -2 are x=1 and x=4.
