Find the The Slop

Given:

y = at x = 4

First, we have to find of given function, f(x),i.e, to find the derivative of f(x)

y =

⇒ y = (

⇒ y =

(xⁿ) = n.x^{n – 1}

The Slope of the tangent is

Since, x = 4

_{x = 4} =

_{x = 4} =

_{x = 4} =

_{x = 4} = 3

The Slope of the tangent at x = 4 is 3

⇒ The Slope of the normal =

⇒ The Slope of the normal =

⇒ The Slope of the normal =
