Express the integral as a function

F$($x$)$

using the evaluation theorem, also known as the Fundamental Theorem of Calculus, part $2,$ which states that if f is continuous over the interval

$[$a$,$ b$]$

and

F$($x$)$

is any antiderivative of

f$($x$),$

then

b

$($integral$)$ f$($x$)$ dx $=$ F$($b$)$ F$($a$).$
