polynomial function‚ we would need to find the three roots to create factors. The roots would be the x-coordinates‚ 6‚ -2‚ and -7 so the factors are x-6‚ x+2 and x+7. Now multiple x-6 and x+2 to get x^2-4x-12. Take that answer and multiply it by the third factor‚x+7 and it would result with x^3+x^2-28x-12x-84. Combine like terms and the polynomial function is f(x) = x^3+x^2-40x-84. 2. Using both fundamental Theorem and Descartes` rule of signs‚ prove to the construction foreman that your function matches

Keweenaw Peninsula‚ conservationists captured‚ tagged‚ and released 50 bears. One year later‚ a random sample of 100 bears included only 2 tagged bears. What is the conservationist’s estimate of the size of the bear population? I will use b for bears and write the expression as follows: B x 100 50 2 I will cross multiply: 50 * 100 = 5‚000 and B * 2 = 2B 5‚000 = 2‚500 2B What is the estimate of the size of the bear population? The answer is 2‚500. In this expression
