Question

Find each value if $f\left(x\right)=5x-9$

$f\left(6\right)$

Step-by-Step Solution

Answer

The value of $f\left(6\right)$ is 21.

Step 1 – Putting value of x

We will put 6 in place of x to determine the value of the function.

Step 2 – Simplifying the given function

As, we have:

$f\left(x\right)=5x-9$

We will put $x=6$:

$\begin{array}{l}f\left(6\right)=5\left(6\right)-9\\ f\left(6\right)=30-9\\ f\left(6\right)=21\end{array}$

Step 3 – Determining the final answer

$f\left(6\right)=21$
