Find the amplitude, period, and phase shift of the function. Graph the function. Be sure to label key points. Show at least two periods. y=4sin(2x-\pi)

∠cbe and ∠deb are same-side interior angles.

i took the test

what shape is

246

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
