**Choosing a Window **Use a graphing calculator or computer to decide which viewing rectangle

**(a)**

**(b)**

**(c)**

**(d)**

To determine

The most appropriate graph of the equation

Explanation

**Given:**

The given equation is,

The rectangular view given are,

(a)

(b)

(c)

(d)

**Approach:**

The graph of the equation using graphing calculator in the given rectangular view is construct on the basis of the following steps:

Step 1: Press the key

Figure

Step 2: Press the key

Figure

Step 3: Press the key

Figure

**Calculation:**

Case (a):

Write the given equation in the graphing calculator,

Start with the viewing rectangle

Set,

The result graph is as shown below,

Figure

The resulting graph is not clear. Some turning point in the graph is not visible in the graph. So this rectangular view is also not appropriate.

Case (b):

Write the given equation in the graphing calculator,

Start with the viewing rectangle
