Question

Is the function linear, quadratic, or exponential?

f(x)=2−3x2+x

Answer 1

No, it is a quadratic function.

Explanation:

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.
