From the graphs of f and g in the figure, we find the following. (Assume that each point lies on the gridlines.)

Question

(f+g)(0)=

(f-g)(0)=

(fg)(0)=

(f/g)(0)=

Answer 1

f(0) = 2 and g(0) = 4 so f + g(0) = 2 + 4 = 6

f(0) = 2 and g(0) = 4 so f - g(0) = 2 - 4 = -2

f(0) = 2 and g(0) = 4 so f • g(0) = 2 • 4 = 8

f(0) = 2 and g(0) = 4 so f / g(0) = 2 / 4 = 0.5
