What is a polynomial function in standard form with zeroes 1, 2, –3, and –3? (1 point)
g(x) = x^4 + 3x^3 –7x^2 – 15x + 18
g(x) = x^4 + 3x^3 –7x^2 + 2x + 18
g(x) = x^4 – 3x^3 + 7x^2 + 15x + 18
g(x) = x4 – 3x3 –7x2 + 15x + 18

hmm srry i dont really know :(

If 1 is a zero then x-1 must be a factor.  If 2 is a zero, then x-2 must be a factor.  If -3 is a zero, then x+3 must be a factor.  If -3 is a zero a second time, then x+3 must be a factor a second time.  Multiply the factors to get the equation.
