Evaluate Using the Given Value f(1)=80e^(-0.7(1))+20

$f (1) = 80 e^{- 0.7 (1)} + 20$

Step 1

Multiply $- 0.7$ by $1$ .

$f (1) = 80 e^{- 0.7} + 20$

Step 2

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

$f (1) = 80 (\frac{1}{e^{0.7}}) + 20$

Step 3

Combine $80$ and $\frac{1}{e^{0.7}}$ .

$f (1) = \frac{80}{e^{0.7}} + 20$
