4-44.
1. Find the general antiderivative, F(x), for each function, f(x), below. Homework Help ✎

1. f(x) = cos x

2. f(x) = −9x1/3

Check your work by differentiating your solution. It's easy to make errors with + and − values.

F(x) = sin(x) + C

Before you antidifferentiate, rewrite f(x) with a negative exponent.

For all of these, don't forget the +C.
