Define a function

Question

Define a function that you might see in a calculus class. Simple functions will not score all points. Your function should have atleast three features. Please identify these features in writing.

Answer 1

What are the features that you are talking about? For example does this function work? f(x)=e^{x}+log(|x|+1). I guess you have three features, that is, an exponential function, a logarithmic function and the absolute value.
