Question

Find the derivative of f(x) = 5 divided by x at x = -1.

Answer 1

@ganeshie8

Answer 2

f(x)=5/x
x=-1
=5/-1
=-5
so that the derivate of the constant is zero

Answer 3

?? @DecentNabeel take derivative first, then replace x =-1 in

Answer 4

f(x) =5 divided by x, means \(f(x) =\dfrac{5}{x}\)

Answer 5

\[\frac{d}{dx}\left(\frac{5}{x}\right)=-\frac{5}{x^2}\]

Answer 6

So the derivative is 5?

Answer 7

or -5?

Answer 8

hen x replace for -1
-5/(-1)^2
=-5/1
=-5

Answer 9

ok
