Let a, b, and c be real numbers where a≠b≠C≠0. Which of the following functions could represent the graph below?

f(x) = x^2(x-a)^2 (x-b)^4 (x-c)

f(x) = x^3(x-a)^3 (x-b) (x-2)^2

f(x) = x^4(x-a) (x-b)^3 (x-c)^3

f(x) = (x-a)^2 (x - b) (x-c)^6

Exercise: counting committees 0.0/2.0 puntos (calificable) we start with a pool of n people. a chaired committee consists of k≥1 members, out of whom one member is designated as the chairperson. the expression k(nk) can be interpreted as the number of possible chaired committees with k members. this is because we have (nk) choices for the k members, and once the members are chosen, there are then k choices for the chairperson. thus, c=∑k=1nk(nk) is the total number of possible chaired committees of any size. find the value of c (as a function of n ) by thinking about a different way of forming a chaired committee: first choose the chairperson, then choose the other members of the committee. the answer is of the form c=(α+nβ)2γn+δ. what are the values of α , β , γ , and δ ?
