1st... You need to divide it into the two sections...

I.e. 0 - 1 and then 1 - 4...

^^Yes; so it would be

abs( integral 0 to 1 of (x-1)^3) + integral 1 to 4 of (x-1)^3

and iirc; the answer is 41/2. i has this exact question in my half yearlies last year

So we have:

1.

2.

3. Which comes down to 1/4 (First equation) + 81/4 (Second equation) = 20 1/2 units^2

Trust this is right.
