The graphs with equations and meet at two points. At one of these points, . What is the value of at the other point?
I dont know how to do this question, I think i should set them equal to each other,
any help appreciated.
I recommend substituting for y as given by the first equation into the second equation. This will given you a quadratic in x. Solve this, then plug the root not equal to 2 into the first equation for x to determine the value of y at the other point.
