Evaluate the Function f(2)=x^3+x^2+x^1+x^0

$f (2) = x^{3} + x^{2} + x^{1} + x^{0}$

Step 1

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

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

Step 2

Simplify the result.

Remove parentheses.

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

Simplify each term.

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

$f (2) = 8 + {(2)}^{2} + 2 + {(2)}^{0}$

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

$f (2) = 8 + 4 + 2 + {(2)}^{0}$

Anything raised to $0$ is $1$ .

$f (2) = 8 + 4 + 2 + 1$

Simplify by adding numbers.

Add $8$ and $4$ .

$f (2) = 12 + 2 + 1$

Add $12$ and $2$ .

$f (2) = 14 + 1$

Add $14$ and $1$ .

$f (2) = 15$

The final answer is $15$ .

$15$
