Choose the equation that represents an exponential function that passes through the point (2, 36).

a. f(x) = 4(3)x
b. f(x) = 4(x)3
c. f(x) = 6(3)x
d. f(x) = 6(x)3

Since we were given only one point, we have to test each exponential function for the point

Since exponential functions are of the form , The correct option is between option A and option C.

For option A,



On substitution, we have;





.

Since the point satisfied the exponential function , the exponential function goes through it.

Hence the correct answer is option A.

No need to test for option C again.
