Factor the expression completely. which is a factor of the given expression? xy + y +3x + 3a) (y + 3)
c.(y - 3)b) (x + 1)
d.(x - 1)

xy + y +3x + 3
y(x + 1) + 3(x + 1)
(y + 3)(x + 1)

Factors: (y+3) and (x+1)

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
