Chapter 2.3, Problem 4E

To determine

To calculate:

Inequality for given function and show by graph.

Answer to Problem 4E

Solution of given equation is $y\le -3$ , so graph is,

  

Explanation of Solution

Given information:

  $3y\le -9$

Calculation:

Here given inequality is $3y\le -9$ ,

Now divide both sides by $3$ and equation will be,

  $\begin{array}{l}3y\le -9\\ \frac{3y}{3}\le \frac{-9}{3}\\ y\le -3\end{array}$

Solution of given equation is $y\le -3$ .

Graph for $y\le -3$ is,
