Homework Statement
X-intercepts: (-1.57,0) , (0.65, 0) , (2.83, 0)
Y-intercept: 11.33
Homework Equations
I've got to convert that information into an estimated cubic function.
The Attempt at a Solution
I tried subbing the y-intercept in; although that didn't work.
11.33 = K(1.57)(-0.65)(-2.83)
11.33 = K(2.888)
K = 3.923
That didn't provide the correct equation when subbed into
f(x)=K(x+1.57)(x-0.65)(x-2.83)
Can anyone help me on this?
