Someone me im begging you dont ignore this i need and i cant understand how to do it explain it to me

see below

Step-by-step explanation:

domain is the certain values x can be

substitute -1,0,1 and 2 in for x

f(-1)=-3-1= -4

f(0)=0-1=-1

f(1)= 3-1=2

f(2)=6-1=5

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)
