CALCULUS!!! tangent lines
posted by Anonymous .
If f(2)=4 and f'(2)=3, use the line tangent to the graph of f at x=2 to find a linear approximation for f(1.992)
HELP! The only one I need, I need a Genius!!!!

y=3x2
f(1.992)=3*1.9922
This is hardly genius material, slope intercept form is algebra I. 
Thanks,yeah now it seems easy, on the board my teacher had a board full of work only for an equation like this, so when I worked on it, i expected it to be more difficult and over analyzed everything. :)
Thanks again. 
you are smart
