I am stuck at the beginning of this question,it is the 8 mark question at the end of last years paper 2.

F(x) comes from the formula 2x- 0.5x2 but where does g(x) come from?

**0**

what do you mean by g(x)?

this question requires u to find the points of intersection between the straight line and the parabola

with this you can then integrate between the points of intersection. You would of course integrate the parabola minus the equation of the straight line

the integral of b a =

f(x) - g(x)

is that the standard equation you use, f(x) = 2x- 0.5x2 how would you get the g(x) equation.

f(x) - g(x)

the "g(x)" part that yo are talking about is the straight line that is y = <whatever the intercept was"
