Translate the following into an inequality: What number plus four is at most 6?

k + 4 ≥ 6
k = 4 < 6
k + 4 ≤ 6
k + 4 > 6

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.

With out knowing the functions you have to chose form, this could be one.y = 5.00xx = hours worked and y = the money he will earn.
