Evaluate each limit using desmos to sketch a graph. 1) lim f(x), f(x) = 1-2, x50 * -+ 0 + (-2x - 8, x> 0 2) lim f(x), f (x) =-*+1, x 2 7) lim f(x), f (x) = -2x - 4, x5-3 8) lim x- 2 (2, x >-3 x - 2 x - 2Evaluate each limit by direct substitution. 9) lim (-x3 + 3x2 + 1) 10) lim (x3 - x2 + 4) X- 1 11) lim Vx + 2 12) lim -V-x +2 x-1 * - - 2 Evaluate each limit using one of the three algebra techniques. 13) lim X ' - x - 6 x2+ 5x +6 14) lim x--2 x + 2 x - - 2 x + 2 Vx + 13 -4 16) lim 2+ x N x -+ 3 15) lim x - 3 x- 0 X x - 3 X 17) lim 18) lim x-3 Vx+1-2 x - - 2 1 2+ x N
