Answer:
-1, 3, y=-3, y=1, y=2, plugging one function into another function
Step-by-step explanation:
Since a function is f(x), you can substitute -2 for x into the equation. Find -2 on the graph and get (-2,-1). For the second question, Again, find x=1 on the graph, which is 3. Third question substitute the x values into the equation to get y=-3, y=1, y=2, and for the last question a function is plugging one function into another function
