"Suppose that I don't have a formula for #g(x)# but I know that #g(1)
= 3# and #g'(x) = sqrt(x^2+15)# for all x. How do I use a linear approximation to estimate #g(0.9)# and #g(1.1)#?"

If
then
This is a standard right angled triangle whose sides are in the ratio:
That is for some constant
We are told that
Therefore
