I believe the answer is C. If any graph doesn't pass the Vertical Line Test(VLT) then it is not a function. I hope this helps love! :)
The answer should be B (5/3, 0)
I am going to go with the assumption that your equation is

. If there is only one solution, then the equation must be a perfect square. So square

to solve for the equation in the similar form that is given.

. So the variables match up perfectly in the equation, meaning that the value of m is 6, letter choice C.
