Graph y=(1/4x)^3

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

Step 1

Find the point at $x = 0$ .

Replace the variable $x$ with $0$ in the expression.

$f (0) = \frac{{(0)}^{3}}{64}$

Simplify the result.

Raising $0$ to any positive power yields $0$ .

$f (0) = \frac{0}{64}$

Divide $0$ by $64$ .

$f (0) = 0$

The final answer is $0$ .

$0$

Convert $0$ to decimal.

$y = 0$

Step 2

Find the point at $x = - 2$ .

Replace the variable $x$ with $- 2$ in the expression.

$f (- 2) = \frac{{(- 2)}^{3}}{64}$

Simplify the result.

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

$f (- 2) = \frac{- 8}{64}$

Cancel the common factor of $- 8$ and $64$ .

Factor $8$ out of $- 8$ .

$f (- 2) = \frac{8 (- 1)}{64}$

Cancel the common factors.

Factor $8$ out of $64$ .

$f (- 2) = \frac{8 \cdot - 1}{8 \cdot 8}$

Cancel the common factor.

$f (- 2) = \frac{8 \cdot - 1}{8 \cdot 8}$

Rewrite the expression.

$f (- 2) = \frac{- 1}{8}$

Move the negative in front of the fraction.

$f (- 2) = - \frac{1}{8}$

The final answer is $- \frac{1}{8}$ .

$- \frac{1}{8}$

Convert $- \frac{1}{8}$ to decimal.

$y = - 0.125$

Step 3

Find the point at $x = - 1$ .

Replace the variable $x$ with $- 1$ in the expression.

$f (- 1) = \frac{{(- 1)}^{3}}{64}$

Simplify the result.

Raise $- 1$ to the power of $3$ .

$f (- 1) = \frac{- 1}{64}$

Move the negative in front of the fraction.

$f (- 1) = - \frac{1}{64}$

The final answer is $- \frac{1}{64}$ .

$- \frac{1}{64}$

Convert $- \frac{1}{64}$ to decimal.

$y = - 0.015625$

Step 4

Find the point at $x = 1$ .

Replace the variable $x$ with $1$ in the expression.

$f (1) = \frac{{(1)}^{3}}{64}$

Simplify the result.

One to any power is one.

$f (1) = \frac{1}{64}$

The final answer is $\frac{1}{64}$ .

$\frac{1}{64}$

Convert $\frac{1}{64}$ to decimal.

$y = 0.015625$

Step 5

Find the point at $x = 2$ .

Replace the variable $x$ with $2$ in the expression.

$f (2) = \frac{{(2)}^{3}}{64}$

Simplify the result.

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

$f (2) = \frac{8}{64}$

Cancel the common factor of $8$ and $64$ .

Factor $8$ out of $8$ .

$f (2) = \frac{8 (1)}{64}$

Cancel the common factors.

Factor $8$ out of $64$ .

$f (2) = \frac{8 \cdot 1}{8 \cdot 8}$

Cancel the common factor.

$f (2) = \frac{8 \cdot 1}{8 \cdot 8}$

Rewrite the expression.

$f (2) = \frac{1}{8}$

The final answer is $\frac{1}{8}$ .

$\frac{1}{8}$

Convert $\frac{1}{8}$ to decimal.

$y = 0.125$

Step 6

The cubic function can be graphed using the function behavior and the points.

$\begin{array}{c} x & y \\ - 2 & - 0.125 \\ - 1 & - 0.016 \\ 0 & 0 \\ 1 & 0.016 \\ 2 & 0.125 \end{array}$

Step 7

The cubic function can be graphed using the function behavior and the selected points.

Falls to the left and rises to the right

$\begin{array}{c} x & y \\ - 2 & - 0.125 \\ - 1 & - 0.016 \\ 0 & 0 \\ 1 & 0.016 \\ 2 & 0.125 \end{array}$
