Differential Equations question

2021 · 27 Aug · Shift 1 · Q28

JEE MainMathematicsDifferential EquationsMCQ+4 / −1
Let us consider a curve, y = f(x) passing through the point (−-− 2, 2) and the slope of the tangent to the curve at any point (x, f(x)) is given by f(x) + xf'(x) = x2. Then :
  1. A
    x2+2xf(x)−12=0{x^2} + 2xf(x) - 12 = 0x2+2xf(x)−12=0
  2. B
    x3+xf(x)+12=0{x^3} + xf(x) + 12 = 0x3+xf(x)+12=0
  3. C
    x3−3xf(x)−4=0{x^3} - 3xf(x) - 4 = 0x3−3xf(x)−4=0
  4. D
    x2+2xf(x)+4=0{x^2} + 2xf(x) + 4 = 0x2+2xf(x)+4=0
