Question

Examples 4 and 5 If $f\left(x\right)=6x+7$ and $g\left(x\right)=x^2-4,$ find each value. (P. 49)

$f\left(m\right)$

Step-by-Step Solution

Answer

The function value at $f\left(m\right)$ is $6m+7$.

Step 1. Interpreting of function.

$f\left(m\right)$ Indicates the value of function $f\left(x\right)$ at $x=m$

Step 2. Apply substitution method.

Substitute $x=m$ into the function $f\left(x\right)$

Step 3. Calculation.

The function value at $-m$ is calculated as follows:

 $\begin{array}{c}f\left(m\right)=6\left(m\right)+7\\ =6m+7\end{array}$

Thus, the function value at $x=m$ is $6m+7$.
