Answer: No, this is not a function
Why not? Because of the points (-7,4) and (-7,6). Both of these points have x = -7. This input leads to multiple outputs, which is not allowed for a function.
Any function must have any input lead to exactly one output.
Visually, this graph fails the vertical line test because of those two points.
the answer to ur question is no, it does not represent a function
