The solution is to use your TI-89 graphing calculator. Example question. What is the limit of 3x2 –3 / x2 –9 as x approaches 0? Step 1: Enter the function into the y1 slot of the “Y=” window. To open the wi
For the following problems, evaluate the limit using the Squeeze Theorem. Use a calculator to graph the functions f(x),g(x)f(x),g(x), and h(x)h(x) when possible. 44. [T] True or False? If 2x−1≤g(x)≤x2−2x+32x−1≤g(x)≤x2−2x+3, then limx→2g(x)=0lim...
(check it out on your calculator) (3) lim x→0 ( 1 x − 1 |x| ). Let f(x) = 1 x − 1 |x| . We write this function as a piecewise defined function: f(x) = 1 x − 1 x = 0 x > 0 1 x + 1 x = 2 x x≤ 0 . 7 lim x→0 ( 1 x − 1 |x| )...
