hardest question of iitjee​

Answer 1

Answer:

hiii

your answer is here !

Step-by-step explanation:

The equation we are given (−at2+bt+c) is a parabola and we are told to describe what happens when we change c (the y-intercept).

From what we know about functions and function translations, we know that changing the value of c will shift the entire parabola upwards or downwards, which will change not only the y-intercept (in this case called the “h intercept”), but also the maximum height of the parabola as well as its x-intercept (in this case called the t intercept). You can see this in action when we raise the value of the y-intercept of our parabola.

Options I, II, and III are all correct.

Our final answer is K, I, II, and III

follow me !

Answer 2

in the given questions the path followed by curve said that the body follow projectile path we know that the projectile path of body depends on

hight

initial as well as final velocity

angle

time

so

option 1,2,and ,3 all are right .
