To evaluate $g(x) = 50e^{-0.1x}$ at $x = -20$, substitute $-20$ for $x$: $g(-20) = 50e^{-0.1(-20)} = 50e^{2}$. Using a calculator, $e^{2} \approx 7.389$, so $50 \times 7.389 = 369.45$, rounded to three decimal places gives $369.453$.

Evaluate the Function as Indicated g(x)=50e−0.1xx=−20\begin{aligned}g ( x ) & = 50 e ^ { - 0.1 x } \\x & = - 20\end{aligned}g(x)x​=50e−0.1x=−20​
