Use algebra and limit laws to find the limits:

a)lim of square root of x+1 - square root of x as x approaches + infinity
b) lim of square root of x^2+x+1 - square root of x as x approaches + infinity
c) lim (x^3-x^2) x as x approaches + infinity

Check you answers by graphing the functions. For example graph lim of square root of x+1 - square root of x for 0<=x<=10000. You may leave the y - range blank.
