The last part of it, the 4 marks.

I say it's 52/3. Dependent on what you get on the Q before.

Someone oppose/confirm?

I make it 52/3 as well. It looks like you do too: 64/3 - 48/2 + 20 = 52/3

Isn't that the area under the shaded region? Shouldn't it be the definite integral of the straight line minus the definite integral of the curve?

This is the area below the curve not the required area.

Using the area of trapezium formula will be faster
5. Isn't it integrating the line from A to B, then taking away the area between the curves given from integrating f(x) - g(x)?
