use the drop - down menu to label the graph according to its type. the graph is a(an): one - to - one function function (but not one - to - one) relation (but not a function)
Answer
Explanation:
Step1: Apply vertical - line test
If any vertical line intersects the graph at most once, it is a function. If it intersects more than once, it is a relation but not a function. For this graph, any vertical line intersects it at most once, so it is a function.
Step2: Apply horizontal - line test
If any horizontal line intersects the graph at most once, it is a one - to - one function. If a horizontal line intersects the graph more than once, it is a function but not one - to - one. Here, a horizontal line can intersect the graph more than once, so it is a function but not one - to - one.
Answer:
function (but not one - to - one)
