Morgan says that the domain of the relation {(2,3), (-4, 2), (0,-4), (1,5)} is {-4, 2, 3, 5}. She is incorrect. Find her mistake and correct it.

State what her mistake was and what the correct domain is for the relation.

Step-by-step explanation:

No she is not correct.

domain are the x co-ordinates (no repetition)

Domain:{-4,0,1,2}

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
