Hi,

I'm trying to create a cubic function that has only one x-intercept of -5 and a y-intercept of around 10.

The y-intercept doesn't have to be exact.

I can't seem to get this as I dont know what to do with the roots.

I get to:

(x+5)(x+-a)(x+-b)

and i dont know what to do from there.

Any help is greatly appreciated.

Thanks,

John
