Use a graphing utility to graph the rational function. Give the domain of the function and identify any asymptotes. Then zoom out sufficiently far so that the graph appears as a line. Identify the line. \(f(x)=\frac{x^{2}+5 x+8}{x+3}\)
The revenue and cost equations for a product are \(R=x(75-0.0005 x)\) and \(C=30 x+250,000,\) where \(R\) and \(C\) are measured in dollars and \(x\) represents the number of units sold. How many units must be sold to obtain a profit of at least \(\$ 750,000 ?\) What is the price per unit?
The graph of a rational function can never cross one of its asymptotes.
Use a graphing utility to graph the rational function. Give the domain of the function and identify any asymptotes. Then zoom out sufficiently far so that the graph appears as a line. Identify the line. \(f(x)=\frac{2 x^{2}+x}{x+1}\)
Use a graphing utility to graph the equation. Use the graph to approximate the values of \(x\) that satisfy each inequality. \(y=\frac{1}{2} x^{2}-2 x+1 \quad\) (a) \(y \leq 0 \quad\) (b) \(y \geq 7\)
