Final answer:
The derivative dy/dx in terms of t without eliminating the parameter is represented by A) dy/dx = 2t.
Step-by-step explanation:
To find dy/dx in terms of t without eliminating the parameter, we can use the chain rule. If y = f(t), then the derivative of y with respect to x, dy/dx, is given by:
dy/dx = (dy/dt) / (dx/dt)
Since the equation is not given, we cannot determine the specific value of dy/dx. Option A, dy/dx = 2t, represents the general form of the derivative. Therefore, the correct answer is A) dy/dx = 2t.
