K- 21 > 1 what us the inequality

Apositive number a or the same number a increased by 50% and then decreased by 50% of the result?

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.

If f(x) = 4x - 3 and g(x) = x + 4, find (f - g) (x)
