Question

The function f (x)is shown in the graph.

What is the equation for f(x)?
Enter your answer in the box.

Answer 1

See below

Explanation:

This is a line with positive slope

pick two convenient integer coordinate points , say (0,-5) and (7,-2)

slope is ( -5 - -2)/ (0-7) = -3/-7 = 3/7

point/ slope line equation form would be (using any of the points on the graph...I will use (7,-2)

(y+2) = 3/7 (x-7) = f(x ) re-arrange to

y = f(x) = 3/7 x -5
