94. What problem do you encounter when using the switch-and- solve strategy to find the inverse of (The switch- and-solve strategy is described in the box on page 235.) 95.25 to what power gives 5? 96. Solve: 1 x - 3 2 2 7 0. 1 25 ? = 5 2 f 1 x 2 = 2 x ? 92. Graph and its inverse function in the same rectan- gular coordinate system. 93. The hyperbolic cosine and hyperbolic sine functions are defined by a. Show that cosh is an even function. b. Show that sinh is an odd function. c. Prove that 1 cosh x 2 2 - 1 sinh x 2 2 = 1. x x cosh x = e x + e - x 2 and sinh x = e x - e - x 2 . f 1 x 2 = 2 x
