You can put this solution on YOUR website!
Exponential functions have the variable, usually x, in the exponent. For example:
h%28x%29+=+2%5Ex

Linear functions do not have squared variables.

So both of your functions are quadratic. They are polynomials of one variable of degree 2. (IOW they have x^2 terms.)
