Given fleftxright fracx22x1x2-x-6 For domain of fleftxright x2 - x - 6 ne 0 therefore leftx-3rightleftx 2 rightne0 Rightarrow x ne 3 -2 therefore Domain of fleftxright is R - left3 -2right. Since the function is defined for all but those x values we just need to exclude them from our domain so we have. X x π 4 π 2 kk Z.
