Chapter 3.6, Problem 7PPS

To determine

To find:an equation in function notation for the given relation.

Answer to Problem 7PPS

  $y=3.33x-2$ or $f\left(x\right)=3.33x-2$

Explanation of Solution

Given:

Given relation

  

Concept used:

Select the points from the graph and plot in a table.

Calculate the difference between the x-values and the y-values.

Calculation:

Consider the given graph.

  

Now, make a table for the points on the graph.

$x$	$0.6$	$0$	$1$	$1.3$
$y$	$0$	$-2$	$1$	$2$

Hence, the required function will be

  $\begin{array}{c}\frac{x}{0.6}-\frac{y}{2}=1\\ 2x-0.6y=1.2\\ y=\frac{2x-1.2}{0.6}\\ y=3.33x-2\end{array}$

or $f\left(x\right)=3.33x-2$
