Question

Find the derivative of f(x) = 6 divided by x at x = -2.

Answer 1

6/x would be 6(x)^-1 exponent rule gets it to -6(x)^-2 so at two it would be -6/4 or -3/2

Answer 2

-1.5

Explanation:

Given that f(x) = 6/x.

The derivative of a function y is also known as dy/dx.

where y = f(x) then the derivative

dy/(dx) = -6(x)^-2

Given that

x = -1

dy/dx = -6 *(2^-2)

= -6/4

= -3/2

= -1.5
