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)=

  • college algebra -

    what's the problem? The roots give the factors:

    1.
    (1)(x+1)(x-2)(x-5)

    2.
    (-1)(x+4)(x-3)(x-3)(x-4)
