Whic statement is true about the local minimum of the
graphed function?
over the interval (-4,-2], the local minimum is 0.
over the interval [-2, -1], the local minimum is 25.
over the interval [-1, 4], the local minimum is 0.
over the interval [4, 7], the local minimum is -7.

2/1 or just 2. sorry if i get this wrong

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.

Can u send a screenshot of it? !
