$f (0) = 80 e^{- 0.7 (0)} + 20$

Step 1

Simplify each term.

Tap for more steps...

Step 1.1

Multiply $- 0.7$ by $0$ .

$f (0) = 80 e^{0} + 20$

Step 1.2

Anything raised to $0$ is $1$ .

$f (0) = 80 \cdot 1 + 20$

Step 1.3

Multiply $80$ by $1$ .

$f (0) = 80 + 20$

$f (0) = 80 + 20$

Step 2

Add $80$ and $20$ .

$f (0) = 100$
