Graph f(x)=x^2(x-1)

$f (x) = x^{2} (x - 1)$

Step 1

Find the point at $x = - 1$ .

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

$f (- 1) = {(- 1)}^{3} - {(- 1)}^{2}$

Simplify the result.

Simplify each term.

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

$f (- 1) = - 1 - {(- 1)}^{2}$

Multiply $- 1$ by ${(- 1)}^{2}$ by adding the exponents.

Multiply $- 1$ by ${(- 1)}^{2}$ .

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

$f (- 1) = - 1 + (- 1) {(- 1)}^{2}$

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$f (- 1) = - 1 + {(- 1)}^{1 + 2}$

Add $1$ and $2$ .

$f (- 1) = - 1 + {(- 1)}^{3}$

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

$f (- 1) = - 1 - 1$

Subtract $1$ from $- 1$ .

$f (- 1) = - 2$

The final answer is $- 2$ .

$- 2$

Convert $- 2$ to decimal.

$y = - 2$

Step 2

Find the point at $x = 0$ .

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

$f (0) = {(0)}^{3} - {(0)}^{2}$

Simplify the result.

Simplify each term.

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

$f (0) = 0 - {(0)}^{2}$

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

$f (0) = 0 - 0$

Multiply $- 1$ by $0$ .

$f (0) = 0 + 0$

Add $0$ and $0$ .

$f (0) = 0$

The final answer is $0$ .

$0$

Convert $0$ to decimal.

$y = 0$

Step 3

Find the point at $x = 2$ .

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

$f (2) = {(2)}^{3} - {(2)}^{2}$

Simplify the result.

Simplify each term.

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

$f (2) = 8 - {(2)}^{2}$

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

$f (2) = 8 - 1 \cdot 4$

Multiply $- 1$ by $4$ .

$f (2) = 8 - 4$

Subtract $4$ from $8$ .

$f (2) = 4$

The final answer is $4$ .

$4$

Convert $4$ to decimal.

$y = 4$

Step 4

Find the point at $x = 3$ .

Replace the variable $x$ with $3$ in the expression.

$f (3) = {(3)}^{3} - {(3)}^{2}$

Simplify the result.

Simplify each term.

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

$f (3) = 27 - {(3)}^{2}$

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

$f (3) = 27 - 1 \cdot 9$

Multiply $- 1$ by $9$ .

$f (3) = 27 - 9$

Subtract $9$ from $27$ .

$f (3) = 18$

The final answer is $18$ .

$18$

Convert $18$ to decimal.

$y = 18$

Step 5

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

$\begin{array}{c} x & y \\ - 1 & - 2 \\ 0 & 0 \\ 1 & 0 \\ 2 & 4 \\ 3 & 18 \end{array}$

Step 6

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

Falls to the left and rises to the right

$\begin{array}{c} x & y \\ - 1 & - 2 \\ 0 & 0 \\ 1 & 0 \\ 2 & 4 \\ 3 & 18 \end{array}$

Step 7
