Which of these is an exponential parent function? o a. f(x) = 2x + 3 o b. f(x) = 2* - 2 o c. f(x) = 24x o d. f(x) = 2x

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

answer is b

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
