Δabc is reflected across the x-axis and then translated 4 units up to create δa′b′c′. what are the coordinates of the vertices of δa′b′c′ ?

answer: (x+2) (x+3) are the binomials for your question : )

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
