Question

Answer 1

Solution:

Given the function below

$f(x)=5x-2$

Where

$\begin{gathered} x\text{ is the input value} \\ f(x)\text{ is the output value} \end{gathered}$

If the input value is 3, i.e. x = 3, the output value will be

$\begin{gathered} f(x)=5x-2 \\ f(3)=5(3)-2=15-2=13 \\ f(3)=13 \end{gathered}$

Hence, the output value is 13
