Ok people its time to don those nice big maths club brains and see if you can sort these out for me.

What is common to graphs of all functions with a negative "a", when in the form f(x)=ax^3 + bx^2 + cx +d.

In the same form what tends to happen when "b" is very large?

What if c and d are 0?

Up to the task I know I am sure as hell not, im trying to think of something to offer as a big reward.

Yr11 maths methods stinks, im never going to be an engineer at this rate.:confused:

They tend to -inf at x=inf, and inf at x=-inf
