Point k lies at (-3,4). Point k is reflected over the y-axis and then translated 7 units down to produce K'. Which rule could have been used to produce K' from K?
K(x, y) +K'(x, y-7)
K(x, y) →K'(-x, y-7)
K(x, y) →K'(x, -y-7)
K(x, y) → K'(-x-7.-y-7)

D. i think it is the savings

Horizontal change or the change of x

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.
