The incidence (number of new cases/day) of a contagious disease spreading in a population of m people is given by i(x) = kx(m − x), where k is a positive constant and x denotes the number of people already infected. find the percentage of the population infected such that the incidence is a maximum.

Use the graph to determine the range. which notations accurately represent the range? check all that apply. (–∞, 2) u (2, ∞) (–∞, –2) u (–2, ∞) {y|y ∈ r, y ≠ –2} {y|y ∈ r, y ≠ 2} y < 2 or y > 2 y < –2 or y > –2
