Evaluate Using the Given Value f(0)=80e^(-0.7(0))+20

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

Step 1

Simplify each term.

Multiply $- 0.7$ by $0$ .

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

Anything raised to $0$ is $1$ .

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

Multiply $80$ by $1$ .

$f (0) = 80 + 20$

Step 2

Add $80$ and $20$ .

$f (0) = 100$
