Write the factored form of the polynomial function with real coefficients, a lead coefficient of 1, and zeros
Kitty [74]

The factored form of the polynomial function is y(x) = (x + 3)²(x - 4)(x - 2)

<h3>How to determine the factored form?</h3>

The given parameters are:

  • Leading coefficient, a = 1
  • Zeros = -3, -3, 4, and 2.

Rewrite the zeros as:

x = -3, x = -3, x = 4 and x = 2

Set the zeros to 0

x + 3 = 0, x + 3 = 0, x - 4 = 0 and x - 2 = 0

Multiply the zeros

(x + 3) * (x + 3) * (x - 4) *(x - 2) = 0

Express as a function

y(x) = a(x + 3) * (x + 3) * (x - 4) *(x - 2)

Substitute 1 for a

y(x) = (x + 3)²(x - 4)(x - 2)

Hence, the factored form of the polynomial function is y(x) = (x + 3)²(x - 4)(x - 2)

evablogger [386]

Answer:

-0.0002x^2 +26x-120000

Step-by-step explanation:

The correct question should be:

We have been told that all we have to do to get profit is to subtract the cost from revenue.

Revenue = 40x - 0.0002x^2

Cost <em>= </em>14x + 120,000<em />

<em />

Hence:

Profit = 40x - 0.0002x^2 - (14x + 120000)

40x - 0.0002x^2 - 14x - 120000\\\\40x - 14x - 0.0002x^2 - 120000\\\\26x - 0.0002x^2 - 120000

Putting it in ordered form:

-0.0002x^2 +26x-120000

This is an expression for the profit.
