Simplify each term.

Multiply ${((1) - 4)}^{2}$ by $1$ .

$f (1) = {((1) - 4)}^{2} + {((1) - 4)}^{2}$

Subtract $4$ from $1$ .

$f (1) = {(- 3)}^{2} + {((1) - 4)}^{2}$

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

$f (1) = 9 + {((1) - 4)}^{2}$

Subtract $4$ from $1$ .

$f (1) = 9 + {(- 3)}^{2}$

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

$f (1) = 9 + 9$

Add $9$ and $9$ .

$f (1) = 18$

The final answer is $18$ .

$18$

Convert $18$ to decimal.

$y = 18$

Step 2

Find the point at $x = 2$ .

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

$f (2) = (2) {((2) - 4)}^{2} + {((2) - 4)}^{2}$

Simplify the result.

Simplify each term.

Subtract $4$ from $2$ .

$f (2) = 2 {(- 2)}^{2} + {((2) - 4)}^{2}$

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

$f (2) = 2 \cdot 4 + {((2) - 4)}^{2}$

Multiply $2$ by $4$ .

$f (2) = 8 + {((2) - 4)}^{2}$

Subtract $4$ from $2$ .

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

$f (3) = (3) {((3) - 4)}^{2} + {((3) - 4)}^{2}$

Simplify the result.

Simplify each term.

Subtract $4$ from $3$ .

$f (3) = 3 {(- 1)}^{2} + {((3) - 4)}^{2}$

Raise $- 1$ to the power of $2$ .

$f (3) = 3 \cdot 1 + {((3) - 4)}^{2}$

Multiply $3$ by $1$ .

$f (3) = 3 + {((3) - 4)}^{2}$

Subtract $4$ from $3$ .

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

Raise $- 1$ to the power of $2$ .

$f (3) = 3 + 1$

Add $3$ and $1$ .

$f (3) = 4$

The final answer is $4$ .

$4$

Convert $4$ to decimal.

$y = 4$

Step 4

Find the point at $x = 4$ .

Replace the variable $x$ with $4$ in the expression.

$f (4) = (4) {((4) - 4)}^{2} + {((4) - 4)}^{2}$

Simplify the result.

Simplify each term.

Subtract $4$ from $4$ .

$f (4) = 4 \cdot 0^{2} + {((4) - 4)}^{2}$

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

$f (4) = 4 \cdot 0 + {((4) - 4)}^{2}$

Multiply $4$ by $0$ .

$f (4) = 0 + {((4) - 4)}^{2}$

Subtract $4$ from $4$ .

$f (4) = 0 + 0^{2}$

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

$f (4) = 0 + 0$

Add $0$ and $0$ .

$f (4) = 0$

The final answer is $0$ .

$0$

Convert $0$ to decimal.

$y = 0$

Step 5

Find the point at $x = 5$ .

Replace the variable $x$ with $5$ in the expression.

$f (5) = (5) {((5) - 4)}^{2} + {((5) - 4)}^{2}$

Simplify the result.

Simplify each term.

Subtract $4$ from $5$ .

$f (5) = 5 \cdot 1^{2} + {((5) - 4)}^{2}$

One to any power is one.

$f (5) = 5 \cdot 1 + {((5) - 4)}^{2}$

Multiply $5$ by $1$ .

$f (5) = 5 + {((5) - 4)}^{2}$

Subtract $4$ from $5$ .

$f (5) = 5 + 1^{2}$

One to any power is one.

$f (5) = 5 + 1$

Add $5$ and $1$ .

$f (5) = 6$

The final answer is $6$ .

$6$

Convert $6$ to decimal.

$y = 6$

Step 6

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

$\begin{array}{c} x & y \\ 1 & 18 \\ 2 & 12 \\ 3 & 4 \\ 4 & 0 \\ 5 & 6 \end{array}$

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

$\begin{array}{c} x & y \\ 1 & 18 \\ 2 & 12 \\ 3 & 4 \\ 4 & 0 \\ 5 & 6 \end{array}$

Step 8
