Select the pair of functions representing f(x) and g(x) if f(g(x)) = 4x + 11. a) f(x) = 4x + 7 and g(x) = x - 3 b) f(x) = 4x - 7 and g(x) = x + 3 c) f(x) = x - 3 and g(x) = 4x + 7 d) f(x) = 4x + 3 and g(x) = x + 2

Describe the end behavior of the function below. f(x)=(2/3)^x-2 a. as x increases, f(x) approaches infinity. b. as x decreases, f(x) approaches 2. c. as x increases, f(x) approaches -2. d. as x decreases, f(x) approaches negative infinity.
