It intersects x - axis at how many points .
There are several different types of functions that each create different types of function graphs. They are a visual representation of data, which often makes it easier for people to see trends and relationships between variables .There are different types of functions that are commonly used, therefore different types of graphs of functions.
According to question , One piece of the graph is parallel to the x- axis , hence it is the graph of a constant function .The other piece is a straight line and intersects the x - axis at exactly one point , therefore , it is graph of a linear function .
