Q:
The number of milligrams \( D(h) \) of a drug in a patient's bloodstrearn \( h \) hours after \( t \)
\[ D(h)=45 e^{-0.35 h} \]
Find the amount of the drug in the bloodstream after 2 hours and after 8 hours.
Round your answers to the nearest hundredth as necessary.
Q:
Graph the rational function.
\[ f(x)=\frac{7}{x-1} \]
Start by drawing the vertical and horizontal asymptotes. Then plot two points on each piece of the graph. Finally, click on the graph-a-function button.
