Answer 1

Answer: Yes

Explanation:

Yes, this is a function

A function is described as a relationship between f(x) and x where each x value corresponds to only 1 y value. A y value can correspond to multiple x values though.

In this picture, the curve only passes each x value once, so yes this is a function.

You can also use the vertical line test.

First, take a vertical line, and move it across the graph. If there is ever more than 1 time where the graph crosses the line, then it is not a function.

Performing this test on this curve, we see that the graph only acrosses the vertical line in one point across the whole graph, so yes this is a function

Answer 2

Yes

Explanation:

In above image use vertical line test to identify whether a relation is a function or not . Vertical line test means draw various vertical lines in graph and it must cut graph only once i.e. every vertical line must intersect graph only once . if lines intersects graph in more than 1 point than relation is not a function . In short, a relation is a function iff for every value of x there's only one value of y , for any case x has 2 or more than 2 values of y it's not a function.
