C3 - Stuck on how to integrate this Watch
Also...Attachment 408759408763 could someone explain to me how to find the range in the first part because they got f(x)<=3 but I got the sign the opposite way around and also how would you go about doing the last part of this question.
Then the normal, the x axis and y the axis form a triangle, I am sure you can work out the area of the triangle!
1/2 x base (B's x co-ordinate) x height (y intercept of the normal).
Then add the value for the curve's integration and the triangle's area and you should have the correct answer!
