Graph y^3=8x

$y^{3} = 8 x$

Find the point at $x = - 1$ .

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

$f (- 1) = 2 \sqrt[3]{- 1}$

Simplify the result.

Remove parentheses.

$f (- 1) = 2 \sqrt[3]{- 1}$

Rewrite $- 1$ as ${(- 1)}^{3}$ .

$f (- 1) = 2 \sqrt[3]{{(- 1)}^{3}}$

Pull terms out from under the radical, assuming real numbers.

$f (- 1) = 2 \cdot - 1$

Multiply $2$ by $- 1$ .

$f (- 1) = - 2$

The final answer is $- 2$ .

$- 2$

Convert $- 2$ to decimal.

$y = - 2$

Find the point at $x = 0$ .

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

$f (0) = 2 \sqrt[3]{0}$

Simplify the result.

Remove parentheses.

$f (0) = 2 \sqrt[3]{0}$

Rewrite $0$ as $0^{3}$ .

$f (0) = 2 \sqrt[3]{0^{3}}$

Pull terms out from under the radical, assuming real numbers.

$f (0) = 2 \cdot 0$

Multiply $2$ by $0$ .

$f (0) = 0$

The final answer is $0$ .

$0$

Convert $0$ to decimal.

$y = 0$

Find the point at $x = 1$ .

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

$f (1) = 2 \sqrt[3]{1}$

$f (1) = 2 \sqrt[3]{1}$

Any root of $1$ is $1$ .

$f (1) = 2 \cdot 1$

Multiply $2$ by $1$ .

$f (1) = 2$

The final answer is $2$ .

$2$

Convert $2$ to decimal.

$y = 2$

Find the point at $x = - 2$ .

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

$f (- 2) = 2 \sqrt[3]{- 2}$

Simplify the result.

Remove parentheses.

$f (- 2) = 2 \sqrt[3]{- 2}$

Rewrite $- 2$ as ${(- 1)}^{3} \cdot 2$ .

Rewrite $- 2$ as $- 1 (2)$ .

$f (- 2) = 2 \sqrt[3]{- 1 \cdot 2}$

Rewrite $- 1$ as ${(- 1)}^{3}$ .

$f (- 2) = 2 \sqrt[3]{{(- 1)}^{3} \cdot 2}$

Pull terms out from under the radical.

$f (- 2) = 2 (- 1 \sqrt[3]{2})$

Simplify the expression.

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

$\begin{array}{c} x & y \\ - 2 & - 2.52 \\ - 1 & - 2 \\ 0 & 0 \\ 1 & 2 \\ 2 & 2.52 \end{array}$

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

Not a polynomial

$\begin{array}{c} x & y \\ - 2 & - 2.52 \\ - 1 & - 2 \\ 0 & 0 \\ 1 & 2 \\ 2 & 2.52 \end{array}$
