A relation is graphed on the set of axes below.
Based on this graph, the relation is
(1) a function because it passes the horizontal line test
(2) a function because it passes the vertical line test
(3) not a function because it fails the horizontal line test
(4) not a function because it fails the vertical line test

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
