Use the set of ordered pairs to determine whether the relation is a function. {(−8,−25),(5,−2),(4,21),(−19,−22),( −17,−1),(−20,−5)}

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.

is there more info provided? there is not enough information given in the problem

the diagram shows you   triangle def with de=4, df=9 and de≠df≠ef.

the sum of the lengths of two triangles' sides are always greater than the length of the third side:

substitute sides lengths:

then 5< ef< 13 (option 3 is true).

def is a scalene triangle with all sides of different lengths (option 5 is true, option 2 is false).

answer: correct choices are 1, 3 and 5
