# Thread: Finding the region under a curve

1. ## Finding the region under a curve

I have two questions here.

1. Find area of region that lies under curve y=(3x+4)1/2 over 0<x<4
(Those are less than or equal to signs)

3. ## Re: Finding the region under a curve

I have trouble finding the antiderivatives.

4. ## Re: Finding the region under a curve

For first one make substitution 3x + 4 = u that gives dx = du/3 and the limits will be from 4 to 16
the question reduces to 1/3 Integral from 4 to 16 ( u^1/2 0 du.
Now you cal finish it.
