(√x+1/√x)^2find dy/ dx and substitute 2 in dy/ dx
lions [1.4K]
Hello,
That's better.

I suppose y=( \sqrt{x} + \dfrac{1}{ \sqrt{x} } )^2 \\

y'=2*( \sqrt{x} + \dfrac{1}{ \sqrt{x} } )*( \dfrac{1}{2 \sqrt{x} } - \dfrac{3}{2x \sqrt{x} } )

If x=2  then
y'=2*( \sqrt{2} + \dfrac{1}{ \sqrt{2} } )*( \dfrac{1}{2 \sqrt{2} } - \dfrac{3}{2*2* \sqrt{2} } )\\
=2* \dfrac{2+ \sqrt{2} }{ \sqrt{2} } * \dfrac{1}{4*\sqrt{2} } *(-1)\\
=- \dfrac{2+ \sqrt{2} }{4}

Answer: (x+3)^2=-4(y-3)

Step-by-step explanation:

From the figure, it is downward parabola of the form x^2=-4ay

The parabola has its vertex at (-3,3)

Distance between parabola vertex and its directrix is 1 unit.

So, the value of a is 1

Hence, the equation of parabola is  (x+3)^2=-4(y-3)
