In Exercises \(83-85,\) use a graphing utility to graph each circle whose equation is given. Use a square setting for the viewing window. $$x^{2}+y^{2}=25$$
What is the graph of a function?
Graph \(y_{1}=\sqrt{2-x}, y_{2}=\sqrt{x},\) and \(y_{3}=\sqrt{2-y_{2}}\) in the same \([-4,4,1]\) by \([0,2,1]\) viewing rectangle. If \(y_{1}\) represents \(f\) and \(y_{2}\) represents \(g\), use the graph of \(y_{3}\) to find the domain of \(f \circ g .\) Then verify your observation algebraically.
Perform the indicated operation or operations. $$(f(x))^{2}-2 f(x)+6, \text { where } f(x)=3 x-4$$
Exercises \(101-103\) will help you prepare for the material covered in the next section. Write an algebraic expression for the fare increase if a \(\$ 200\) plane ticket is increased to \(x\) dollars.
