Answer:
by definition, an exponential function with base c is defined by h (x) = ac^x
where a ≠0, c > 0 , b ≠1, and x is any real number.
The base, c, is a constant and the exponent, x, is a variable.
so if we have f(x)=3(3\8)^2x, this equivalent to f(x)=3(3\8)^y(x),
where y (x)=2x,
therefore, the base is 3/8, and the variable is the function y (x)=2x, it is 4
