Real Analysis Functions with Equal Derivatives - Let f be a function given by
x + 2 if x < 0
f(x) =
x if x >= 0
Is there a function g: R ---> R such that g'=f?
*be careful applying definition of the derivative
Evaluating Functions using Derivatives - Let f be a function that is differentiable for all real numbers. The table gives the values of f and its derivative f' for selected points x in the closed interval -1.5
