Diana invested some money in a bank at a fixed rate of interest compounded annually. the equation below shows the value of her investment after x years: f(x) = 400(1.01)x what was the average rate of change of the value of diana's investment from the second year to the fifth year?

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.

It is blindness and randomization
