Concept:
First eliminate the t from x=3t and then put it in y=t² and then graph it. As, limit of t is not restricted so t ∈ R(all real numbers)
As it is difficult to make graph here so I have solved it by hand and add all detail regarding it.
3/4 is .75 so you do .75 multyplyed by 6 and get 4 1/2. Hope I helped!
Answer: Sometimes
Step-by-step explanation: Through every 2 points is a line, so it would be sometimes as a line only has a minimum of 2 points.
