Chapter 9, Problem 24SGR

To determine

To state: Graph the function and state domain and range.

Answer to Problem 24SGR

Domain is $\left\{x|x\ne 0\right\}$ and range is $\left\{f\left(x\right)|f\left(x\right)\ne 0\right\}$ .

Explanation of Solution

Given information:

The given function is $f\left(x\right)=\frac{10}{x}$ .

Calculation:

For the function $f\left(x\right)=\frac{a}{x-h}+k$ .

The vertical asymptotes is at $x=h$ . And

The horizontal asymptotes is at $y=k$ .

The domain of the function is all real number except the value at the vertical asymptotes and the range of the function is all real number except the value at the horizontal asymptotes.

The graph of the given function is drawn below:

  

From the above graph:

  $h=0$ and $k=0$ .

Therefore,

Domain: $\left\{x|x\ne 0\right\}$

Range : $\left\{f\left(x\right)|f\left(x\right)\ne 0\right\}$

Hence,

Domain is $\left\{x|x\ne 0\right\}$ and range is $\left\{f\left(x\right)|f\left(x\right)\ne 0\right\}$ .
