the graph of a function f is given. use the horizontal - line test to determine whether f is one - to - one.
the graph of a function f is given. use the horizontal - line test to determine whether f is one - to - one.
Answer
Explanation:
Step1: Understand horizontal - line test
The horizontal - line test states that a function (y = f(x)) is one - to - one if and only if no horizontal line intersects the graph of the function more than once.
Step2: Examine the given graph
Draw horizontal lines across the graph of the function (f). We can see that there are horizontal lines (for example, (y = 3)) that intersect the graph of the function at two points.
Answer:
The function (f) is not one - to - one.
