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

Answer:

See below

Step-by-step 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
