If you were given the function y=4x-3 and you had to find the Range, given the Domain: (1,3,5,7) which one would be correct?

1. (1,5,9,13)
2. (3,9,12,15)
3. (1,9,17,31)
4. (1,9,17,25)

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.

The answer to your question is b
