The degree of the polynomial function f(x) is 3. the roots of the equation f(x)=0 are -1, 0, and 4. which graph could be the graph of f(x)

answer:

the answer should be the top right.

step-by-step explanation:

roots given are -1, 0 and 4. which means the graph intercept at x-axis at -1, 0 and 4.

plus, polynomials with degree 3 means the highest power of x is cubic x. which means it will be a cubic graph. the two graph at the top is cubic graph while the two at the bottom is quadratic graph

d? maybe

step-by-step explanation:

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
