Answer the question.Why can't we call y = (-2)x an exponential function?
What will be an ideal response?
Because the definition of an exponential function, f(x) = ax, includes a restriction that 
This is necessary so that the function can be defined for all real numbers x. Letting a be negative 
in this case) and letting 
would yield the expression (-2)1/2, which is, of course, not real.
