Question

By the Second Fundamental Theorem of Calculus, if $F'=f$ on $[a,b]$, then $\int_a^b f(x)\,dx$ equals

Accepted Answer

B. $F(b)-F(a)$

1. The theorem states $\int_a^b f(x)\,dx=[F(x)]_a^b$.
2. This means upper-limit value minus lower-limit value.
3. Hence $\int_a^b f(x)\,dx=F(b)-F(a)$.

Answer

$F(a)-F(b)$

Answer

$F(b)+F(a)$

Answer

$F'(b)-F'(a)$
