Question

Using the substitution u = 2x+1, the integral from 0 to 2 of sqrt(2x+1)dx is ...?
(set up integral; do not evaluate)

Answer 1

\[\int\limits_{0}^{2} \sqrt{2x+1}dx\]
when u = 2x+1

Answer 2

do the limits change?

Answer 3

cuz i got \[\frac{ 1 }{ 2 } \int\limits_{0}^{2}\sqrt{u}du \] as the answer

Answer 4

That's fine. Go on.

Answer 5

ok that's all i needed.
