$f (x) = 80 e^{- 0.5 \cdot 1} + 20$

Step 1

Multiply $- 0.5$ by $1$ .

$f (x) = 80 e^{- 0.5} + 20$

Step 2

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$f (x) = 80 (\frac{1}{e^{0.5}}) + 20$

Step 3

Combine $80$ and $\frac{1}{e^{0.5}}$ .

$f (x) = \frac{80}{e^{0.5}} + 20$
