Question
Select the second function in "The Limit of a Function", y = √x.
(a) Set a = 5 and 8 = 0.2. Use the 0-slider to find a value for & so that f(x) is within 0.2 of f(5) for all values of x where 5 - 0 < x < 5 +6. What is the largest value of you can use?
(b) Use the graph to estimate the largest value of so that I√x -21 < 0.3 whenever Ix - 4| < 0.
(c) Zoom in at x = 3, and estimate the largest value of so that √x - √3|< 0.01 whenever |x - 3|< 6.
(d) State the limit that part (c) is illustrating.
lim √x =
x-3
