please explain part f and how to answer it. will you glance at a-e and confirm if they are correct. Thank you

F ( X ) = x +5 , X21 # 10 * - 3 a ) " * = 1 - 1 7+* 7 X71 a) lim x+5 = - 1+5 - 4 =-1 X7 - 1+ x-3 - 1- 3 - 4 two 7 *71 b) lim 7+x = 10 X-3- () lim X +5 = 1+5 - 6 = 3 X-71- X- 3 1 - 3 2 d) lim z+x = 7+1 =8 X >T X - 21+ () Does the limit f(x) exist ? No because X -71 lim =3 * lim = 8 50 378 X -71 - X-It so the limit DNEILL F) Is the Function F continuous at x=1
