Chapter 9.1, Problem 1QR

To determine

To Calculate: The value of a function at a given value.

Answer to Problem 1QR

The value of $f\left(5\right)$ is $\frac{5}{8}=0.625$

Explanation of Solution

Given Information: The function is $f\left(x\right)=\frac{x}{x+3}$ and the value of $x$ is $5$

Method: Put the given value of $x$ in the expression of the function and evaluate.

Calculation: Put $x=3$ in the expression for $f\left(x\right)$ to get

  $f\left(5\right)=\frac{5}{5+3}$

  $=\frac{5}{8}$

  $=0.625$

Therefore, the value of $f\left(5\right)$ is $0.625$
