Find the most general antiderivative of the function. (check your answer by differentiation. use c for the constant of the antiderivative.) f(x) = 7x + 3 sinh(x)

Step-by-step explanation:

The antiderivative is found applying the fundamental theorem of calculus:

Where a is any number where f(x) is a continuous function.

Here, the antiderivative is

The antiderivative requires to integrate f(x), we apply first the polynomials rule

For this case n=1 and the first part of the integral  is:

The integral of sinh(x) is cosh(x), so, the total antiderivative is
