Given this equation for converting temperature from Celsius (c) to Fahrenheit (f) is C = [5(f – 32)]/9, what is the Celsius temp when Fahrenheit is 104 degrees?​

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.
