Answer to: Determine whether the statement, if a function is differentiable at point (a, f(a)), then f(x) is continuous at x = a, is true or false...
is differentiable at the given point. If f′(a) exists, give its value. f(x)=x1/5+5 (a) a=1 (b) a=0Differentiability:If a function is differentiable at a point then its derivative exists at that point. In other words, the slope of ...
Suppose that a function f is differentiable on (0, +\infty) and that \lim_{x\rightarrow +\infty} \frac{f(x)}{x} = 0 . Prove that there exists a sequence x_n \gt 0 such that \lim x_n = + \ Prove that if f_n\ \to\ f uniformly on an interval I and each f_...

A line like x=[1,2,3], y=[1,2,100] might or might not represent a differentiable function, because even a smooth function can contain a huge derivative in one point. There is also no to "proove" if sin(1/x) is differentiable in x=0 if all you have is a finite number of ...
