PLEASE HELP does this graph represent a function? why or why not?

a. no, because it fails the vertical line test.

b. yes, because it is a curved line.

c. no, because it is not a straight line.

d. yes, because it passed the vertical line test.

Yes, it is a function

Step-by-step explanation:

If you were to draw a straight vertical line through it, it would only hit the line once, and therefore is a function. Curved lines can still be functions.

So the correct answer is d) yes, because it passed the vertical line test.

Hope this helps! Best of luck <3
