Chapter 12.1, Problem 1AYU

For the function $f\left(x\right)\text{ = }\frac{x-\text{ 1}}{x}$, find $f\left(2\right)$ and $f\left(3\right)$. (pp.60-63)

To determine

To find: For the function $f\left(x\right)\text{ = }\frac{x-\text{ 1}}{x}$, find $f\left(2\right)$ and $f\left(3\right)$.

Answer to Problem 1AYU

$f\left(2\right)=\frac{1}{2}$ and $f\left(3\right)=\frac{2}{3}$.

Explanation of Solution

Given:

$f\left(x\right)\text{ = }\frac{x-\text{ 1}}{x}$

Calculation:

$f\left(x\right)\text{ = }\frac{x-\text{ 1}}{x}$

$f\left(2\right)=\frac{2-1}{2}=\frac{1}{2}$

$f\left(3\right)=\frac{3-1}{3}=\frac{2}{3}$
