$f (1) = 90 e^{- 0.5 (1)} + 10$

Step 1

Multiply $- 0.5$ by $1$ .

$f (1) = 90 e^{- 0.5} + 10$

Step 2

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

$f (1) = 90 (\frac{1}{e^{0.5}}) + 10$

Step 3

Combine $90$ and $\frac{1}{e^{0.5}}$ .

$f (1) = \frac{90}{e^{0.5}} + 10$
