Hi everybody, i just joined. Here's my first post I have a few questions. When looking at curve C and by the eye test, it doesn't pass the VLT, even though x=f (t ) and y=g (t) are functions,....then overall with curve C not passing the VLT, is it still a function since f (t) and g (t) are? I feel like curve C is still a function because it just shows the path of the parametric equations based on coordinates that are functions. Is my understanding correct on this assumptios? 2nd question Can parametric equations take in f (t) and g (t) as relations or will there be an error of some sort? 3rd Is there any relation or similarites (maybe in graphs) between compositing functions vs parametric equations? Thanks in advance!
