Chapter 9: Q28. (page 594)

Describe how the graph of each function is related to the graph of $f (x) = x^{2}$ .
$f (x) = \frac{1}{4} x^{2}$

Short Answer

Expert verified

The graph $f (x) = \frac{1}{4} x^{2}$ is the graph vertically compressed from the parent function $f (x) = 鈥夆赌� x^{2}$ .

Step by step solution

Step 1. State the concept.

Vertical Stretch and Vertical Compression:

$y = a f (x), a > 1$ . Sketch the graph $f (x)$ vertically by a factor of a.

$y = a f (x), 0 < a < 1$ . Compress the graph $f (x)$ vertically by a factor of a.

Step 2. Graph each function.

The graph of the functions $f (x) = x^{2}$ and $f (x) = \frac{1}{4} x^{2}$ is given by:

Step 3. State the interpretation of the graph.

The graph of $f (x) = a x^{2}$ stretches or compress the parent graph vertically. Since $a = \frac{1}{4}$ , the graph of $f (x) = \frac{1}{4} x^{2}$ is the graph of $f (x) = x^{2}$ vertically compressed. Compress the graph of $f (x)$ vertically by a factor of $\frac{1}{4}$ .

Therefore, the graph $f (x) = \frac{1}{4} x^{2}$ is the graph of vertically compressed from the parent function $f (x) = x^{2}$ .
