️JKL has vertices J(-5, 5), K(-2, 7), and L(1, 3). List the coordinate for J' after a reflection in the X-axis.

Ibelieve the answer would be 7, 13, 23

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 would be 10.
