Can someone plz me with this p

We can choose one of this points to graphed to the given coordinate system

and makes relation which is not function

e.g. (-4, 2) , (-2, -4) , (0, 1) , (2, 2) , (4, 4)  Why?

Definition of the function is - Every element of the starting set (domain-x) must be related to only one element of the second set ( codomain-range-y).

If you add any of this points e.g. (-4, 2) then you have an existing point on the graph (-4, -1)

In that situation you have coordinate x=-4 which is in relation with two coordinates y=2 and y=-1 and that is relation not function.

Good luck!!!

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

hope this !
