Graph Using a Table of Values f(x)=4/x

$f (x) = \frac{4}{x}$

Step 1

Substitute $- 2$ for $x$ and find the result for $y$ .

$y = \frac{4}{- 2}$

Step 2

Divide $4$ by $- 2$ .

$y = - 2$

Step 3

Substitute $- 1$ for $x$ and find the result for $y$ .

$y = \frac{4}{- 1}$

Step 4

Divide $4$ by $- 1$ .

$y = - 4$

Step 5

Substitute $1$ for $x$ and find the result for $y$ .

$y = \frac{4}{1}$

Step 6

Solve the equation for $y$ .

Remove parentheses.

$y = \frac{4}{1}$

Divide $4$ by $1$ .

$y = 4$

Step 7

Substitute $2$ for $x$ and find the result for $y$ .

$y = \frac{4}{2}$

Step 8

Solve the equation for $y$ .

Remove parentheses.

$y = \frac{4}{2}$

Divide $4$ by $2$ .

$y = 2$

Step 9

This is a table of possible values to use when graphing the equation.

$\begin{array}{c} x & y \\ - 2 & - 2 \\ - 1 & - 4 \\ 1 & 4 \\ 2 & 2 \end{array}$
