Chapter 1: Q15. (page 49)

Examples 4 and 5 If $f (x) = 6 x + 7$ and $f (x) = 6 x + 7$ find each value. (P. 49)
$g (a) + 9$

Short Answer

Expert verified

The value of the function $g (a) + 9$ is $a^{2} + 5$

Step by step solution

Step 1. Interpreting of function.

$g (a)$ Indicates the value of function $g (x)$ at $x = a$

Step 2. Apply substitution method.

Substitute $x = a$ into the function $g (x)$

$g (a) = a^{2} - 4$

Step 3. Calculation.

$\begin{array}{l} g (a) + 9 = a^{2} - 4 + 9 \\ g (a) + 9 = a^{2} + 5 \end{array}$

Therefore, the value of the function $g (a) + 9$ is $a^{2} + 5$
