Answer:
Step-by-step explanation:
We want to find the polynomial function whose zero are -1 and 4i.
Recall that non-real zeros come in pairs.
There if 4i is a zero, then the conjugate -4i is also a zero.
Therefore the factors of this polynomial are:
x+1, x+4i, and x-4i are factors of the given polynomial.
Let f(x) be the required polynomial, then we can write the polynomial in factored form as:
We expand the conjugate pair using difference of two squares to get:
Expand further using the distributive property to get:
Answer:
Step-by-step explanation:
We are told that P(x) is the profit of saling x blu ray discs. P(1000) is our profit for selling 1000 blu ray discs. So, our profit is 5000. Recall that the derivative P'(x) represents the rate at which the function P(x) is increasing/decreasing (increasing if P'(x) is positive, or decreasing otherwise) by increasing the values of x. In this case P'(1000)=-3, so the profit will decrease -3 if we increase x in one unit.
