$f (1) = 80 e^{- 0.6 (1)} + 20$

Step 1

Multiply $- 0.6$ by $1$ .

$f (1) = 80 e^{- 0.6} + 20$

Step 2

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

$f (1) = 80 (\frac{1}{e^{0.6}}) + 20$

Step 3

Combine $80$ and $\frac{1}{e^{0.6}}$ .

$f (1) = \frac{80}{e^{0.6}} + 20$
