NOW YOU SOLVE THIS! Use Table of Values and Graphing to determine the limits of the following functions. If the limit does not exist, write DNE(Does not exist). You may use desmos or geogebra in your graph. 1. lim Bx2tx+3 4. lim x2-16 7. lim 1+ - 2 lim 1+ 2 ,and lim 1 + (#7 one graph only) X-3 x-4 X--4 x+4 x-+2 x-2 x-2+ X-2 x-+2 2. lim -1 5. lim Vx-4 x -1 x+2 x-4 x-4 3. lim 5x + 2 6. lim 3x2 - 9
