Is #f(x)= 3x^2# an exponential function? Algebra Quadratic Equations and Functions Linear, Exponential, and Quadratic Models 1 Answer Kevin B. · Nghi N. Jun 3, 2015 No, it is a quadratic function. An exponential function has the variable as the exponent. #3^x# would have been an example of an exponential function. In this function, the exponent is not variable, it is #2#. Therefore this is a quadratic function, not an exponential one. Answer link Related questions What is the linear regression line?
