Which polynomial when factored gives the zeros for the polynomial shown in the graph? -) A) x3 + 8x2 + 21x + 18 B) x3 - 2x2 - 9x + 18 x3 - 4x2 – 3x + 18 D) x3 - 8x2 + 21x - 18​

Respuesta :

The function of the polynomial graph when factored is (d) [tex]f(x) = x^3 - 8x^2+ 21x - 18[/tex]

From the question (see attachment), we have the following highlights:

  • The graph crosses the x-axis at x = 2.
  • The graph touches the x-axis at x = 3

This means that:

  • The graph has a multiplicity of 1 at x = 2
  • The graph has a multiplicity of 2 at x = 3

So, the function of the graph is:

[tex]f(x) = (x - 2)(x - 3)^2[/tex]

Expand the exponent

[tex]f(x) = (x - 2)(x^2 - 6x + 9)[/tex]

Expand

[tex]f(x) = x^3 - 6x^2 + 9x - 2x^2 + 12x - 18[/tex]

Collect like terms

[tex]f(x) = x^3 - 6x^2 - 2x^2+ 9x + 12x - 18[/tex]

[tex]f(x) = x^3 - 8x^2+ 21x - 18[/tex]

Hence, the function of the graph is (d)
