What is the input value for which f(x)=3?

The input value is -3

Step-by-step explanation:

In the diagram above, it is given that y = f(x). The question ask us to find the value of input which is x value when f(x) = 3 :

f(x) = 3

y = 3

By looking at the graph,

When y = 3,

x = -3

i think is g(1)=-1.

hope that i can

table 3 represents a direct variation function. : )
