Question

How do you find the stretch factor of a polynomial?

Answer 1

well I would normally substitute a point that lies on the curve

so for a quadratic

y= p(x -3)(x - 5)


you would normally be given a point on the curve (x, y).

by substituting into the equation, you can find the value of p

here are some notes as well

Answer 2

How would you do it for one with these points (x+3)(x+2)(x-3)^2 and no point was given?

Answer 3

umm... i'd assume the stretch factor is 1.
