E) $0.535$

Quizplus · Accepted Answer

To evaluate $h(x) = e^{-x}$ at $x = \frac{5}{8}$, substitute $\frac{5}{8}$ for $x$ to get $h\left(\frac{5}{8}\right) = e^{-\frac{5}{8}}$. Using a calculator to find $e^{-\frac{5}{8}}$ gives approximately $0.535$, rounded to three decimal places.

Evaluate the Function at the Indicated Value of X h(x)=e−xh ( x ) = e ^ { - x }h(x)=e−x
