These are the ones I'm having trouble with. Any help would be much appreciated. Thanks.
using f(x+h)-F(x)/h
F(x)=1/x^2
what is
F(1/x^2+h)-(1/x^2)/ h
Not too sure what the first step would be
2x+5 -3<x<0 that should be -3 is less than or equal to x
f(x)=-3 x=0
-5x x>0
I need to find the domain and intercepts. How do I go about doing that in these equations.
The volume V of a right circular cylinder of height h and radius r is
V=pi r^2 h. If the height is twice the radius, express the volume V as a function of r
