So if you see x^2, then it means x raised to the power of 2, which is to say x squared or . If you only see x^, then the writer is incorrectly using the symbol, probably to mean x^2, i.e. .
1 The function $f(x)=e^{x}$ is a function which is very important in calculus. It appears in many applications. 2  The exponential function arises whenever a quantity grows or decays at a rate proportional to its current value.  The graph of $y=e^x$lies between the graphs of $y=2^x$ and $y=3^x$.
