Your wage is \(\$ 12.00\) per hour plus \(\$ 0.55\) for each unit produced per hour. So, your hourly wage \(y\) in terms of the number of units produced \(x\) is \(y=12+0.55 x.\) (a) Find the inverse function. What does each variable in the inverse function represent? (b) Use a graphing utility to graph the function and its inverse function. (c) Use the trace feature of the graphing utility to find the hourly wage when 9 units are produced per hour. (d) Use the trace feature of the graphing utility to find the number of units produced per hour when your hourly wage is \(\$ 21.35\)
An air traffic controller spots two planes flying at the same altitude. Their flight paths form a right angle at point \(P\). One plane is 150 miles from point \(P\) and is moving at 450 miles per hour. The other plane is 200 miles from point \(P\) and is moving at 450 miles per hour. Write the distance \(s\) between the planes as a function of time \(t.\)
Determine whether the function is even, odd, or neither (a) algebraically, (b) graphically by using a graphing utility to graph the function, and (c) numerically by using the table feature of the graphing utility to compare \(f(x)\) and \(f(-x)\) for several values of \(x\). $$f(x)=x^{6}-2 x^{2}+3$$
Prove that a function of the following form is odd. $$y=a_{2 n+1} x^{2 n+1}+a_{2 n-1} x^{2 n-1}+\cdots+a_{3} x^{3}+a_{1} x$$
Think About It A function \(f\) is increasing over its entire domain. Does \(f\) have an inverse function? Explain.
