Step 1.1

Raise $8$ to the power of $2$ .

$f (8) = 0.25 \cdot 64 - 1.5 \cdot 8 + 2.5$

Step 1.2

Multiply $0.25$ by $64$ .

$f (8) = 16 - 1.5 \cdot 8 + 2.5$

Step 1.3

Multiply $- 1.5$ by $8$ .

$f (8) = 16 - 12 + 2.5$

$f (8) = 16 - 12 + 2.5$

Step 2

Simplify by adding and subtracting.

Step 2.1

Subtract $12$ from $16$ .

$f (8) = 4 + 2.5$

Step 2.2

Add $4$ and $2.5$ .

$f (8) = 6.5$

$f (8) = 6.5$
