The mapping shows a relationship between input and output values. Which ordered pair could be removed to make this relation a function? (–5, 0) (–1, –3) (4, –2) (6, –1)
At first glance, a function looks just like a relation. Like a relation, a function has
a domain and range made up of the x and y values of ordered pairs. A test
known as vertical line test is used to know if the relation is a function,
since the given data has different y values then it can already form a relation
function without omitting a single point
