### A class is trying to eliminate t from the parametric equations x=t^2+3 and y=4t. Beth says that she can write t= the square root of (x-3) to eliminate the parameter. Why is this wrong? A)She should have added 3 to x, not subtracted. B)She should always solve for t as a function of y. C)She should have taken both the positive and negative square root. D)She should first substitute y for t before solving. I think it might be C, but I'm not sure.
