a) Determine an equation, in simplified form, for the family of cubic functions with zeros 2 +- sqrt5 and 0
b) Determine an equation for the member of the family with graph passing through point (2,20)
Homework Answers
it would be
y = ax(x-2)(x+√5)(x-√5)
= ax(x-2)(x^2 - 5)
to find a, sub in your given point (2,20)
y = x^3 - 4x^2 - x
