Question

Which set represents the range of the function shown?

{(-1,5),(2,8),(5,3),(13,-4)}

A- {-1,2,5,13}
B-{-4,3,5,8}
C- {(5,-1),(8,2),(3,5),(-4,13)}
D-{-4,-1,2,3,5,5,8,13}

Answer 1

Choice B is the correct answer.
The range is the y values.
Always remember domain comes first, then range.
So we can see that the range includes: 5,8,3,-4
We must simply put it in numerical order: -4,3,5,8 and we see it has a match with B.

Answer 2

B. {-4,3,5,8}

Explanation:

We are given,

The set representing the function is {(-1,5),(2,8),(5,3),(13,-4)}.

It is required to find the range set of the function.

Now, as we know,

In the ordered pair
`(x,y)`, the y co-ordinate 'y' represents the range values of a function.

So, we see that,

The range values of the given function are 5, 8, 3 and -4.

Thus, the set representing the range of the function is {-4,3,5,8}.
