Evaluate The Graph And Deturmin If Y Is A Function Of X class=

Sagot :

Determining if a graph is a function of x

We know a function is determined by the following condition:

each value of x (input) has one value of y (output) related.

Using the vertices line test we have that there are not inputs with more than one output.

But there are x values with no y values related, then this is a function but this is not a function of x, because there are x values with no output.

Answer: y is not a function of x, it is a function of a subset of x
