Final answer:
To convert parametric equations x=f(t) and (t) to a Cartesian equation, one typically solves for t and substitutes into x=f(t) and y=g(t).
Step-by-step explanation:
To convert parametric equations x=f(t) and (t) to a Cartesian equation, one typically solves for t and substitutes into x=f(t) and y=g(t). So the correct answer is A) x=f(t) and B) y=g(t). This allows us to eliminate options C) y=x and D) x²+y²=1, as they are not the correct methods for converting parametric equations to Cartesian equations.
