It's a cubic with a positive x^3 coefficient. The general shape is "/".
It goes to -∞ for large negative x.
It goes to +∞ for large positive x.
So if we take 1/4 to be the 100%, what is 2/3 in percentage off of it then?

yes, is a large value, because 2/3 is indeed larger than 1/4, more than twice as large.
The answer would be that the dot falls on the point (0,4)
Answer:
D
Step-by-step explanation:
Where f(0) is or x=0, y= 4
Step-by-step explanation:
2tan 30° / 1 + tan² 30° =
2(⅓√3) /1 + (⅓√3)² =
⅔√3 / 1+ ⅓ =
⅔√3 / 4/3 =
2/4 √3 =
½√3 = sin 60° (proven)
