Evaluate Using the Given Value f(2)=2^2+4(2)-5

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

Step 1

Simplify each term.

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

$f (2) = 4 + 4 (2) - 5$

Multiply $4$ by $2$ .

$f (2) = 4 + 8 - 5$

Step 2

Simplify by adding and subtracting.

Add $4$ and $8$ .

$f (2) = 12 - 5$

Subtract $5$ from $12$ .

$f (2) = 7$
