Question

Determine which relation is a function.

A.
{(–5, 1), (–5, 0), (–2, 1), (–1, 4), (6, 2)}

B.
{(–5, 1), (–2, 0), (–2, 2), (3, 4), (6, 2)}

C.
{(–5, 1), (–2, 0), (–1, 1), (2, 4), (6, 3)}

D.
{(–5, 3), (–2, 0), (–1, 2), (6, 4), (6, 3)}

Answer 1

give a metle

Answer 2

For it to be a function, each x can only have one y value assigned to it. The reverse isnt true (so one y can be assigned to 2 x's). Therefore, the answer is C.

Answer 3

can i ask you some more

Answer 5

I dont think your question loaded but for determining which is a function just remember that it can only have 1 x value to 1 y value (as I said before), so just skim through each x value in each set and if there is more than one of the same value for the x (like for instance x=2 appears twice) then it is NOT a function.

Answer 6

Which relations are functions?

Choose all answers that are correct.

A.
{(1, 4), (2, 5), (4, 6), (6, 4)}

B.
x 0 2 3 2
y 4 3 8 1


C.
A set of points are plotted on a coordinate grid. The points include point 1, 2... point negative 1, 4... point negative 2, 2... point 3, 4... point 2, 6... point negative 3, 6... and point negative 4, 3.

D.
A parabola, opening right, is graphed on a coordinate grid. The parabola goes through point 0, 2, point 4, 0, and point 4, 4.

Answer 7

you tell me:) Ill tell you if you are right or wrong. (HINT only 2 right answers here)

Answer 8

a and c

Answer 9

yes you are correct
Nce!

Answer 10

there is an easier way though by mapping. so u need to make sure every x value has only one y value associated with it
