a. The function *x*^{3} is the simplest function whose derivative is 3*x*^{2}, so b. is the collection of all functions with derivative *e*^{x}. The function *e*^{x} is its own derivative and antiderivative. This means any antiderivative of *e*^{x} looks like *e*^{x} plus some constant. c. Every antiderivative of 0 is a constant, so |
