(2) For each of the following functions, construct a table of values of x over the indicated interval and then graph the function.
(a) y = e0.5x [-3,3] (b) f(x) = 2e-x [-3,3] (c) h(x) = -e-x [-3,3]SOLUTION:
(a) y = e0.5x [-3,3] x y --- ----- -3 0.223 -2 0.368 -1 0.607 0 1.000 1 1.649 2 2.718 3 4.482(b) f(x) = 2e-x [-3,3] x y --- ----- -3 40.17 -2 14.78 -1 5.437 0 2.000 1 0.736 2 0.271 3 0.100 (c) h(x) = -e-x [-3,3] x y --- ------- -3 -20.09 -2 -7.389 -1 -2.718 0 -1.000 1 -0.368 2 -0.135 3 -0.050
