Find the zeros of the polynomial function: <br> f(x) = 9x^3 - 27x^2 - 4x + 12.
hichkok12 [17]

Answer:

  {-2/3, 2/3, 3}

Step-by-step explanation:

The equation can be factored by grouping.

  f(x) = (9x^3 -27x^2) +(-4x +12)

  f(x) = 9x^2(x -3) -4(x -3)

  f(x) = (9x^2 -4)(x -3)

We recognize the first factor as the difference of squares, so know it can be further factored to give ...

  f(x) = (3x -2)(3x +2)(x -3)

The zeros are the values of x that make these factors be zero:

  3x -2 = 0   ⇒   x = 2/3

  3x +2 = 0   ⇒   x = -2/3

  x -3 = 0   ⇒   x = 3

The zeros of the polynomial are x = -2/3, 2/3, 3.

A farmer is tracking the amount of corn his land is yielding each year. He finds that the function f(x) = −x2 + 20x + 50 models
zysi [14]

Answer:

The crop yield decreased by 0.09 pounds per acre from year 1 to year 10

Step-by-step explanation:

The function that models the crops in pounds per acre over x years is

f(x)=-x^2+20x+50

In year 1, the crop yield is f(1)=-(1)^2+20(1)+50=69

In year 10, the crop yield is f(10)=-(10)^2+20(10)+50=150

The average rate of change from year 1 to year 10 is given by:

\frac{f(10)-f(1)}{10-1}

We substitute the values to get:

\frac{150-69}{10-1}

=\frac{81}{9}=9

Since the average rate of change is positive, the crop yield decreased by 0.09 pounds per acre from year 1 to year 10.
