Find the most general antiderivative of the function. (Check your answer by differentiation. Use C for the constant of the antid
Alex

Answer:

F(x) = \frac{x^3}{3} - \frac{7x^2}{2} + 5x + c

Step-by-step explanation:

The antiderivative of a function (also called the integration of a function) is the reverse of the differentiation of that function. Given a function f(x), its integration, F(x), can be calculated as follows;

F(x) = \int\limits{f(x)} \, dx

From the question, f(x) = x² - 7x + 5

Therefore,

F(x) = \int\limits {(x^2 - 7x + 5)} \, dx

F(x) = \frac{x^3}{3} - \frac{7x^2}{2} + 5x + c

Where c is the constant of the integration (antiderivative).

PS: The constant of integration is used for indefinite integrals and allows to express integration of a function in its most general form.

mihalych1998 [28]
Subtract 2.2 from both sides leaving -2n on the left and 10 on the right. from there you want to get "n" by itself so you divide both sides by -2n and you get n=-5

2.2-2n=12.2
-2.2 -2.2

-2n = 10
/-2 /-2

n=-5
