Which point could be removed in order to make the relation a function? {(0, 2), (3, 8), (–4, –2), (3, –6), (–1, 8), (8, 3)} which point could be removed in order to make the relation a function? {(0, 2), (3, 8), (–4, –2), (3, –6), (–1, 8), (8, 3)}

ANSWER: Either or

Explanation

For a relation to be a function, it must either be a one-to-one relation or many-to-one-relation.

The above relation is one-to-many relation because 3 is mapping on to -6 and 8.

To make the above relation a function, we must remove one of the points containing 3 as first coordinate.

This will make the relation one-to-one which then becomes a function.

See attachment for diagrammatic representation.

step-by-step explanation:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
