Chapter 1: Q44. (page 50)

Examples 4 and 5 If $f (x) = 鈭� 2 x 鈭� 3$ and $g (x) = x^{2} + 5 x,$ find each value. (P. 50)
$3 [g (n)]$

Short Answer

Expert verified

The value of the function is $3 n (n + 5)$

Step by step solution

Step 1. Interpreting of function.

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

Step 2. Apply substitution method.

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

$\begin{array}{l} g (n) = {(n)}^{2} + 5 n \\ g (n) = n^{2} + 5 n \end{array}$

Step 3. Further calculation.

$\begin{array}{l} 3 [g (n)] = 3 [n^{2} + 5 n] \\ 3 [g (n)] = 3 n^{2} + 15 n \\ 3 [g (n)] = 3 n (n + 5) \end{array}$

Thus, the value of the function is $3 n (n + 5)$
