According to a height and weight chart, bruce's ideal wrestling weight is 168 pounds. bruce
wants to keep his weight within 3 pounds of his ideal weight. let x equal bruce's actual
weight. solve the equation 1x – 168] = 3 to find bruce's maximum and minimum weights.

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.
