Question

F ( x ) = 0.1 ( 3 x − 2 ) aWhat is the value of f ( 5 ) ?

Answer 1

3

Explanation:

First, plot the graph of the function

and the graph of the line

This line intersects the graph of the function f(x) at 4 different points. So, there are 4 different values for b at which

Only 3 of them have positive values.

At these positive values, f(x)=2 (because the graph of the function and the graph of the line y=2 intersect at these points), then for these three b with positive values,
