Explain how to use a graph of the function f(x) to find f(3).

In the graph locate the point (3,0) and draw a line parrallel to Y-axis passing through (3,0) . Then your line will cut the graph of f(x) at some point, that point's y-coordinate will be your value of f(3)

how is that middle school

step-by-step explanation:

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y
