Answer:
x = -3, -2, or 2
Step-by-step explanation:
In the graph, we can look along the line f(x)=6 and see where the function intersects, noting the x-coordinate of each value. We see that the coordinates with a y-value of 6 are (-3, 6), (-2, 6), and (2,6). This means that x can equal either -3, -2, or 2 when f(x)=6.
