Graph Using a Table of Values y=(3/4)^x

$y = {(\frac{3}{4})}^{x}$

Step 1

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

$y = {(\frac{3}{4})}^{- 2}$

Step 2

Solve the equation for $y$ .

Remove parentheses.

$y = {(\frac{3}{4})}^{- 2}$

Simplify ${(\frac{3}{4})}^{- 2}$ .

Change the sign of the exponent by rewriting the base as its reciprocal.

$y = {(\frac{4}{3})}^{2}$

Apply the product rule to $\frac{4}{3}$ .

$y = \frac{4^{2}}{3^{2}}$

Raise $4$ to the power of $2$ .

$y = \frac{16}{3^{2}}$

Raise $3$ to the power of $2$ .

$y = \frac{16}{9}$

Step 3

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

$y = {(\frac{3}{4})}^{- 1}$

Step 4

Solve the equation for $y$ .

Remove parentheses.

$y = {(\frac{3}{4})}^{- 1}$

Change the sign of the exponent by rewriting the base as its reciprocal.

$y = \frac{4}{3}$

Step 5

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

$y = {(\frac{3}{4})}^{0}$

Step 6

Solve the equation for $y$ .

Remove parentheses.

$y = {(\frac{3}{4})}^{0}$

Simplify ${(\frac{3}{4})}^{0}$ .

Apply the product rule to $\frac{3}{4}$ .

$y = \frac{3^{0}}{4^{0}}$

Anything raised to $0$ is $1$ .

$y = \frac{1}{4^{0}}$

Anything raised to $0$ is $1$ .

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

Divide $1$ by $1$ .

$y = 1$

Step 7

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

$y = {(\frac{3}{4})}^{1}$

Step 8

Solve the equation for $y$ .

Remove parentheses.

$y = \frac{3}{4}$

Remove parentheses.

$y = \frac{3}{4}$

Step 9

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

$y = {(\frac{3}{4})}^{2}$

Step 10

Solve the equation for $y$ .

Remove parentheses.

$y = {(\frac{3}{4})}^{2}$

Simplify ${(\frac{3}{4})}^{2}$ .

Apply the product rule to $\frac{3}{4}$ .

$y = \frac{3^{2}}{4^{2}}$

Raise $3$ to the power of $2$ .

$y = \frac{9}{4^{2}}$

Raise $4$ to the power of $2$ .

$y = \frac{9}{16}$

Step 11

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

$\begin{array}{c} x & y \\ - 2 & \frac{16}{9} \\ - 1 & \frac{4}{3} \\ 0 & 1 \\ 1 & \frac{3}{4} \\ 2 & \frac{9}{16} \end{array}$
