Graph Using a Table of Values f(x)=6^(-x)

$f (x) = 6^{- x}$

Step 1

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

$y = 6^{- (- 2)}$

Step 2

Simplify $6^{- (- 2)}$ .

Multiply $- 1$ by $- 2$ .

$y = 6^{2}$

Raise $6$ to the power of $2$ .

$y = 36$

Step 3

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

$y = 6^{- (- 1)}$

Step 4

Simplify $6^{- (- 1)}$ .

Multiply $- 1$ by $- 1$ .

$y = 6^{1}$

Evaluate the exponent.

$y = 6$

Step 5

Substitute $0$ for $x$ and find the result for $y$ .

$y = 6^{- (0)}$

Step 6

Simplify $6^{- (0)}$ .

Multiply $- 1$ by $0$ .

$y = 6^{0}$

Anything raised to $0$ is $1$ .

$y = 1$

Step 7

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

$y = 6^{- (1)}$

Step 8

Simplify $6^{- (1)}$ .

Multiply $- 1$ by $1$ .

$y = 6^{- 1}$

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$y = \frac{1}{6}$

Step 9

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

$y = 6^{- (2)}$

Step 10

Simplify $6^{- (2)}$ .

Multiply $- 1$ by $2$ .

$y = 6^{- 2}$

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$y = \frac{1}{6^{2}}$

Raise $6$ to the power of $2$ .

$y = \frac{1}{36}$

Step 11

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

$\begin{array}{c} x & y \\ - 2 & 36 \\ - 1 & 6 \\ 0 & 1 \\ 1 & \frac{1}{6} \\ 2 & \frac{1}{36} \end{array}$
