Question

Please help!!!
Find a formula for the polynomial of least degree through the points (-4,0) (2,2) (4,0)

Answer 1

start with
\[y=a(x+4)(x-4)=a(x^2-16)\] then you can solve for \(a\) because you know if \(x=2\) then \(y=2\) solve
\[a(2^2-16)=2\] for \(a\)

Answer 2

I tried that and I keep getting the equation y=(-2/12)(x+4)(x-4) but web work says it's wrong

Answer 3

looks like a will simplify
