Which is not a function
An ordered pair is represented as:

However, for the ordered pair to be a function; all the x values must be unique (i.e. not repeated)

For this case, what we are going to do first is to assume that all the exams are worth the same percentage of the final grade.
We have then that Lisa's average grade point equation is:

Where,
x: minimum note that lisa must obtain in the last exam.
Clearing x we have:
Answer:
the lowest grade she can get on her last test is:
x = 94
