Hey I'm currently in Caculus AB and I have gotten 95-100 in all my other math classes and wanted to try and help out other people with math problems cause idk but some people find the simplest things so hard.

I'll try to answer your questions as best I can cause somethings I have forgotten. You know how it is...

Everybody who is in high school is takeing Ap Calulos because your only supposed to go to Pre Cal.

didnt know that, but i guess it makes sense. can you help me with this:
there is a tangent line for y=g(x) at (2,4) and the tangent line has a point of (9,0) find g(2) and g'(2)
i no that g(2)=4 but i dont know the rest

g'(2) would be the slope of the tangent line at x=2. you can calculate this by:

m=(y2-y1)/(x2-x1)=(0-2)/(9-4)=-2/5
g'(2)=-2/5

Yeah I already send him a private message about this. And you were on the righ trac but your numbers are messed up because the 4 is supposed to be with the 0 and the 2 is supposed to be witht he 9
