Question

If ƒ = {(5, 1), (6, 2), (7, 3), (8, 1), (9, 7)}, then the range of ƒ is:

Answer 1

ANSWER

$R:\lbrace1,2,3,7\rbrace$

EXPLANATION

We want to identify the range of the given function.

The range of a function is the set of all y values of the function. In other words, it is the set of all output values of the function.

The given points are in the form:

$f=(x,y)$

Therefore, the range of the function is:

$R:\lbrace1,2,3,7\rbrace$

That is the answer.
