Here's the question you clicked on:

All values of x are differentiable for the function, f=x^2 f'=2x I believe that this statement is true, but my notes appear to say otherwise. Am I right or my notes right?
The function \(f(x)=x^2\) is indeed differentiable over \(\mathbb{R}\).
Thanks! Just wanted to be sure.
