Finding X Intercepts of Polynomials

Given the factored form: f(x) = x(x -3)(x +2)

• (3,0) (-2,0)

• (0,0) (3,0) (-2,0)

• (0,0) (-3,0) (2,0)

• (3,0) (2,0)

If the x- intercepts of a cubic polynomial are (-2,0)(0,0)(5,0), the possible function would be:

• f(x) = (x - 2)(x + 5)

• f(x) = x(x - 2)(x + 5)

• f(x) = x(x + 2)(x - 5)

• f(x) = x²(x +2)(x - 5)

If the x- intercepts of a quartic polynomial are (-2,0)(0,0)(5,0), the possible function would be:

• f(x) = (x - 2)²(x + 5)

• f(x) = x(x - 2)(x + 5)

• f(x) = x(x + 2)(x - 5)

• f(x) = x²(x + 2)(x - 5)

Solve the polynomial by finding all the zeros of the function: f\left(x\right)=x^4+x^3-7x^2-x+6

• x=1, x= -2, x=4

• x= 2i, x= -2i, x= 3, x= 6

• x= 1, x= -1, x= 2, x= -3

• x= 6, x= -6, x= 1, x=-3

• -4, -1, 3

• 3, -3, 4, 1

• 4, 1, -3

• 3, -4, -1, 3
