If f(x) = 3x + 10x and g(x) = 2x - 4, find (f+ g)(x). O A. 3X – 8x+4
O B. 3x + 12x - 4
O C. 15x - 4
O D. 3x + 8x + 4

please note it’s (f+g)(x) not (f-g)(x)

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.
