Chapter 9: Q23. (page 594)

Describe how the graph of the function $f (x) = x^{2} + 8$ is related to the graph $f (x) = x^{2}$ .

Short Answer

Expert verified

The graph of the parent function is shifted up to 8 units.

Step by step solution

Step 1. Define the standard form of the quadratic function.

A quadratic function, which is written in the form, $y = a x^{2} + b x + c$ , where, $a 鈮� 0$ is called the standard form of the quadratic function.

Step 2. Define vertical translation of the graph.

The graph $g (x) = x^{2} + c$ is the graph $f (x) = x^{2}$ translated vertically.

If $c > 0$ , the graph $f (x) = x^{2}$ is translated $|c|$ units up.

If $c < 0$ , the graph $f (x) = x^{2}$ is translated $|c|$ units down.

Step 3. Determine the relationship of the graph of the function fx=x2+8 with the graph of the function fx=x2.

Observe the function $f (x) = x^{2} + 8$

Here, $c = 8$

So, the graph of the parent function is translated 8 units up to form the graph of the function $f (x) = x^{2} + 5$ .

Therefore, the graph of the parent function is shifted to 8 units.
