1.write the formula for the function that has degree 3 and zeros of 1,2 and 5 with a lead coefficient of 1? (leave answer in factored form)
f(x)=
2. Write the formula for the function that has degree of 4 and zeros of 4, 3(multiplicity 2) and 4 with a lead coefficient of 1? (leave answer in factored form)
f(x)=

what's the problem? The roots give the factors:
1.
(1)(x+1)(x2)(x5)
2.
(1)(x+4)(x3)(x3)(x4)
