4. Find where the functions are continuous. a. x)= ff: b. f(x)=/4x6 5. Sketch the graph of the given function using horizontal and vertical asymptotes. 5+x x)=x_3 x+2 x2 - 2x 1. a. lim X- - 0 X- x-6 b. lim 2x + 1 X-+00 2. f(x) = x+1 x 2 - 9 a. lim f(x) x-+3+ b. lim f(x) x-+ 3- c. lim f(x) x-+3 3. Use the graph to answer the following questions 7 5 -6 - 5 -4 -3 -2 2 3 4 AX a. (i) lim f(x) (ii) f(2) x-2 (iii) Is the function continuous at x =2? Explain. b. (i) lim f(x) (ii). f(4) X--4 (iii) Is the function continuous at x =4? Explain
