Representing Operations Graphically Use the graph to find f(-2) + g(-2). Check your work by finding f(x) + g(x) algebraically. Then evaluate for x = -2

25
Representing Operations Graphically Use the graph to find g(0) x f(0). Check your work by finding g(x) x f(x) algebraically. Then evaluate for x=0
