Question

For $f\left(x\right)=2x–3$ finding each value.

$6–f\left(5\right)$

Step-by-Step Solution

Answer

The value $6-f\left(5\right)$ is –1

Step 1. From question.

The given expression is $f\left(x\right)=2x-3$

Step 2. To find.

Find the value of $6-f\left(5\right)$ for $f\left(x\right)=2x-3$

Step 3. Evaluation.

Putting $x=5$ in $6-f\left(5\right)$, we get

$\begin{array}{l}6-f\left(5\right)=6-\left(2\left(5\right)-3\right)\\ =6-\left(10-3\right)\\ =6-7\\ =-1\end{array}$

Hence, the value of $6-f\left(5\right)$ for $f\left(x\right)=2x-3$ is $(-1)$.
