Question

Given f(x) and g(x) = f(x) + k, use the graph to determine the value of k.

Answer 1

Answer: C) 4

All points on the blue curve f(x) are shifted up 4 units to get corresponding points on the red curve g(x). For example, the point (0,-3) moves up 4 units to (0,1).

g(x) = f(x)+k

g(x) = f(x)+4
