A Math · Secondary 4 · Hard · Tangents and normals

The curve

y = 5 + \dfrac{3}{(x+2)^2}

intersects the

y

-axis at point

B

. Find the equation of the normal to the curve at

B

.

$y = \dfrac{4}{3}x + \dfrac{23}{4}$
$y = -\dfrac{3}{4}x + \dfrac{23}{4}$
$y = \dfrac{3}{4}x + \dfrac{23}{4}$
$y = -\dfrac{4}{3}x + \dfrac{23}{4}$
