Answer:
Step-by-step explanation:
I'm fairly certain you have an error in your equation as the curve you suggests opens upward so has no maximum profit. Profit becomes positive on completion of the 7th unit. (curve crosses x axis at (6.056, 0))
I will GUESS that the equation should read
P(x) = - 2x² + 120x – 800
Maximum will occur when the derivative is zero (zero slope)
P(x) = -2x² + 120x – 800
P'(x) = -4x + 120
0 = -4x + 120
x = 30
P(30) = -2(30)² + 120(30) – 800
P(30) = $1000

Answer:
f(x) = x^6 -10x^5 +89x^4
Step-by-step explanation:
For a given zero p with multiplicity n, one of the factors of the polynomial will be (x -p)^n. If the polynomial has real coefficients, then the complex zeros come in conjugate pairs.
The factored form of your polynomial is ...
f(x) = (x -(5 -8i))(x -(5 +8i))(x -0)^4
f(x) = ((x -5)^2 -(8i)^2)(x^4) = (x^2 -10x +89)(x^4)
f(x) = x^6 -10x^5 +89x^4
