$f(5) = -\frac{14}{3}(125) + 33(25) - \frac{211}{3}(5) + 45 = -\frac{1750}{3} + 825 - \frac{1055}{3} + 45$

Key Insights

Step 1: Evaluate the multiplicative terms involving fractions.

First, compute each fraction multiplied by the numbers:

−14/3 × 125 = −(14 × 125)/3 = −1750/3
33 × 25 = 825
−211/3 × 5 = −(211 × 5)/3 = −1055/3

So, the expression becomes:

f(5) = −1750/3 + 825 − 1055/3 + 45
