Which polynomial function can be represented by the graph below
s344n2d4d5 [400]

<u>Answer:</u>

The correct answer option is C. f(x)=-2x^3-2x^2+12x.

<u>Step-by-step explanation:</u>

From the given graph of the polynomial function, we can see that the graph passes through the following points: (-3,0), (0,0) and (2,0).

So the roots or zeros of this polynomial function are: -3,0 and 2.

Now, we'd graph the equation of the given polynomial and will check for roots and end behavior of the graph.

Therefore, the polynomial function that is represented by the graph is:

f(x)=-2x^3-2x^2+12x

f(3) is x = 3

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em>:                    f(3) = -5(3) - 2
  2. Multiply:                               f(3) = -15 - 2
  3. Subtract:                              f(3) = -17
