current skill $ is this a function? yes no
Answer
Explanation:
Step1: Recall the vertical line test
A relation is a function if for every (x -)value there is exactly one (y -)value. The vertical line test states that if a vertical line intersects the graph of a relation at more than one point, then the relation is not a function.
Step2: Analyze the given graph
Looking at the graph, for each (x) in the domain of the relation, there is exactly one (y) associated with it. When we consider the concept of a function (y = f(x)), where for an input (x) (from the set of (x -)values for which the function is defined), there is a unique output (y). In this piece - wise graph, no vertical line will intersect the graph at more than one point.
