Answer:

Step-by-step explanation:
The function <em>F(x)</em> is an antiderivative of the function <em>f(x)</em> on an interval <em>I</em> if
<em>F′(x)</em> = <em>f(x)</em> for all <em>x </em>in <em>I</em>.
The function <em>F(x) + C</em> is the General Antiderivative of the function <em>f(x)</em> on an interval <em>I</em> if <em>F′(x) = f(x)</em> for all <em>x</em> in <em>I </em>and <em>C</em> is an arbitrary constant.
The Indefinite Integral of <em>f(x)</em> is the General Antiderivative of <em>f(x)</em>.

To find the first antiderivative you must integrate the function 

To find the second antiderivative you must integrate the function 

Therefore,
