The graph of a function g(a:) is given below. (All interesting features have integer coordinates.) 12 a) List the points a: = a. at which 11m 9(33) does not exist. :cm a: [a FORMATTING: if there is more than one solution, separate them with a semicolon(;). if there is no such point, type empty. b) List the points as : b at which 9 is discontinuous. b : a . FORMATTING: if there is more than one soiution, separate them with a semicoion(;). if there is no such point, type empty
