Given a position function s=f(x), which describes the distance of a particle, in inches, at a given time, measured in seconds, from a starting point, describe the meaning, in words, of
f'(2)=10

True or False
A function can have a non-zero first derivative and a zero second derivative.
True
True or false:
A function can be differentiable at a point, but not continuous there.
False
