K(x) = 3(2) {}^(x) - 8. Is the function linear, quadratic, exponential or neither?

Question

`k(x) = 3(2) {}^(x) - 8`. Is the function linear, quadratic, exponential or neither?

Answer 1

An exponential function is defined as a function of the form:

`f(x)=a(b)\placeholder{⬚}^x+c`

where a, b and c are constants.

We notice that the function given has this form, therefore the function given is an exponential function.
