# Math Help - instantaneous rate of chang

1. ## instantaneous rate of chang

Estimate the instantaneous rate of change of ${h}{\left({x}\right)}=\frac{{3}}{{{x}+{6}}}$ at the point ${x}=-{1}$

2. u must know the following to solve this problem:
1)instantaneous rate of chnge is given by d/dx.
2)at the point means the value of f'(x) at that point of f(x).
