Answer:
The answer to your question is No
Step-by-step explanation:
To answer this question use the Vertical line test. This test states that if we draw a vertical line and intercepts the function only in one point it is a function.
It the vertical line intersects the graph in two or more points, it is not a function.
See the picture below
The graph given is not a function because the vertical line crosses the graph in three points.
Answer:
Step-by-step explanation:
The test to see if the inverse function is also a function is called the "horizontal line test." The test passes if any horizontal line intersects the graph in only one place.
Here, a horizontal line can intersect the graph in 1, 2, or 3 places, so the test fails. The function does not have an inverse that is a function.
__
If the domain of the inverse relation is restricted to |x| > 1.2, then that inverse will map any x to only a single value of y. Then it will be a function.
_____
The graph shows the original function (dashed red line) and the inverse relation (blue). The green shading marks values of x for which there is a single value of y, so the inverse relation is a function in those regions.
(We could be more specific as to the limits on the domain of f^-1(x), but the given graph seems to have an unknown vertical scale factor.)
