How can you determine whether a relation represents a function?

Use the vertical line test if you have a graph or check if every input x has one output y

Ifound this on google “a skewed (non-symmetric) distribution is a distribution in which there is no such mirror-imaging. a "skewed right" distribution is one in which the tail is on the right side. a "skewed left" distribution is one in which the tail is on the left side. the above histogram is for a distribution that is skewed right.” i hope this you for what your looking for

Can u send a screenshot of it? !
