1. The problem statement, all variables and given/known data
Ok, I have a cubic function, y=(x6)(x1)(x9) or y = x^{3}16x^{2}+69x54 I then have four tangents to make a quadrilateral, the tangents are as follows. y=7.75x+14.75 y=6.25x+56.25 y=7.75x + 76.231 y=6.25x + 31.602 I need to find the area inside the tangents, except I have no idea where to start, Thankyou for any help in advance.

y=7.75x+14.75 & y=7.75x + 76.231 y=6.25x+56.25 & y=6.25x + 31.602 What sort of quadrilateral figure is formed?

Or you could split the area into two triangles and calculate it.
