pls help

1. Draw the graph of a function that is defined for all real numbers and is continuous everywhere except at x = 4 where there is a removable discontinuity (3 points). 2. Draw the graph of a function, f(x) that is continuous and defined on [-1, 4) only and lim f(x) = 3 (3 points) x - 4- 3. Draw the graph of one function, f(x) that has all of the following features: (4 points) a. f(2) = 1 b. lim f(x) = -4 x -+ 2 c. lim f(x) = -2 x - 0+ d. lim f(x) = 2 X - 0
