"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)#?"

The Y-intercept is 3.
Explanation:
You have a slope intercept equation here- y=mx+b. With m representing the slope and b representing the y-intercept. Therefore, with the equation y=(1/3)x+3, your slope is going to be 1/3 (rise over run) and your y-intercept is going to be positive 3.
