$f (1) = 60 e^{- 0.4 (1)} + 40$

Step 1

Multiply $- 0.4$ by $1$ .

$f (1) = 60 e^{- 0.4} + 40$

Step 2

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

$f (1) = 60 (\frac{1}{e^{0.4}}) + 40$

Step 3

Combine $60$ and $\frac{1}{e^{0.4}}$ .

$f (1) = \frac{60}{e^{0.4}} + 40$
