From: JEE Main 2021 (Online) 27th August Morning Shift
Question
Let y = y(x) be the solution of the differential equation
such that y(0) = 7. Then y() is equal to :
such that y(0) = 7. Then y() is equal to :
Choose an option
Show full solutionCorrect option: A
Correct answer
A
Step-by-step explanation
IF =
So,
Given at x = 0, y = 7
7 = 5 + c c = 2
So,
Now, at x = ,
y = 5 + 2
