What function is the inverse of the exponential function y = (1.5)x?

Correct question is;

What function is the inverse of the exponential function y = 1.5^(x)?

y = log_1.5_x

Step-by-step explanation:

The inverse of exponential functions is usually written in form of logarithm.

For example inverse of y = p^(x) will be written as; y = log_p_(x)

Similarly applying this same pattern to our exponential function y = 1.5^(x), we have the inverse as;

y = log_1.5_x
