Answer:
Box 1: 4
Box 2: -2
Step-by-step explanation:
A) f(1)=?
This is asking us what is at x=1??
So we look at the graph and x=1 y is at 4!
so therefore, f(1) = 4
Next...
now its asking the opposite what is f(x)=1
In other words what is x when y is 1??
So when looking at the graph, x is -2 when y is at 1!!
Therefore, f(-2) =1
