Answer: a: -2, b: 0

Step-by-step explanation:

f(2) means that x=2, and we need to solve for y.

On the graph, it has a point of (2, -2) and since it's a function that is the only possible output. Therefore, f(2)=-2.

f(x)=-4 means that y=-4, and we need to solve for x.

On the graph, the point (0,-4) exists, and since the function contains only one output, it must be correct. Therefore, x=0.
