Show that if a function is differentiable for an interval, it is continuous over that interval. A function is continuous if lim_x->a f(x) = f(a)

There are 2 definitions for the derivative, either would be useful in the proof Solution spoiler https://gmtex.siri.sh/fs/1/School/Extra/Maths/Qotd solutions/2024-05-15_differentiablility-implies-continuity.html
