Answer:
a = 60
Step-by-step explanation:
90 + 30 = 120
120 - 180 = 60
Given a polynomial and a point , we have that
We know that our cubic function is zero at -4, 0 and 5, which means that our polynomial is a multiple of
Since this is already a cubic polynomial (it's the product of 3 polynomials with degree one), we can only adjust a multiplicative factor: our function must be
To fix the correct value for a, we impose :
And so we must impose
So, the function we're looking for is
No correlation is suggested
