Solve the inequality and graph the solution on the real number line. Use a graphing utility to verify your solution graphically. $$2 x^{3}+3 x^{2}<11 x+6$$
Solving an Equation Involving Fractions Find all solutions of the equation. Check your solutions. $$\frac{1}{x}-\frac{1}{x+1}=3$$
Find the inverse function. $$y=12 x$$
Completely factor the expression over the real numbers. $$x^{3}+5 x^{2}-2 x-10$$
Graphical Analysis (a) use a graphing utility to graph the equation, (b) use the graph to approximate any \(x\) -intercepts of the graph, (c) set \(y=0\) and solve the resulting equation, and (d) compare the result of part (c) with the \(x\) -intercepts of the graph. $$y=2 x-\sqrt{15-4 x}$$
