Evaluate 4x3 + 2 for x = -1. Simplify -|-7 + 4|..
Simplify 7m - 11n - n + 5m
Simplify 6(x + 3).
Simplify 8 - {x - (5 + x)}..
Evaluate 7 + (-4x2) for x = 0.

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.

So confused right here i need it to be more clearer
