Homework Equations
The Attempt at a Solution
My question is.. If youre given information like this ::
a) A quintic function with zeroes at -2(o3) and 3(o2) and that has a y intercept at 70.
From this statement, are you able to determine the value of the leading coefficiant ( ALWAYS?)
So a) would be.. y = (x+2)^3 (x-3)^2 + 70
If i set X = 0, then y= (0+2)^3 (0-3)^2 + 70
Which gives me (2)^3 * (-3)^2 which is 72.
Do i then do the y intercept value over the value of setting the f(0) ?
Like The leading coefficiant for this one would be 70/72(x+2)^3(x-3)^2 + 70
Is that correct?
Plz answer!
In the back of the book the "+70" is gone.. So that represents a vertical stretch of that value instead of the y intercept? I am confused. Why is that the coefficiant
