The concentration \(C(t)\) of a drug in a patient's bloodstream \(t\) hours after administration is given by $$C(t)=\frac{4 t}{3+t^{2}}$$ where \(C(t)\) is in milligrams per liter. During what time interval will the concentration be greater than 1 milligram per liter?
Solve the rational inequality. $$\frac{x-1}{x+2} \geq 0$$
Solve the rational inequality. $$\frac{1}{x} \leq \frac{1}{2 x-1}$$
Give a possible expression for a rational function \(r(x)\) of the following description: the graph of \(r\) has a horizontal asymptote \(y=0\) and a vertical asymptote \(x=0,\) with no \(x\) - or \(y\) -intercepts. It may be helpful to sketch the graph of \(r\) first. You may check your answer with a graphing utility.
Sketch a graph of the rational function and find all intercepts and slant asymptotes. Indicate all asymptotes onthe graph. $$h(x)=\frac{x^{2}-9}{x}$$
