I have done this question but when I draw the graph of Lo(x) I dont get a linear function...I get some weird looking graph kinda U shaped. its above f(x) so I think I have the wrong answer.. the question is find the linear approximation of x/sqrt(X+1) at x=0, use the linearization to approximate f(0.03)
my answer, linear approx= x/(sqrt(x+1))+(2+x)/(2 (1+x)^(3/2))(x-0)
The Lo graph isnt linear though or atleast maybe my scale is wrong...I really need help. Am I wrong? what am I doing wrong?
