Unformatted text preview: x 6 = 3. (a) In part (a) we’re asked for the limit as x approaches 3 from the left , so lim x → 3f ( x ) = lim x → 3( x + 2) =5 (b) The limit in part (b) is as x approaches 3 from the right , so lim x → 3 + f ( x ) = lim x → 3 + ( x + 2) = 5 (c) From parts (a) and (b), the lefthand and righthand limits of f are not the same for x approaching 3, so the limit of f ( x ) as x → 3 does not exist. That is, lim x → 3 f ( x ) = DNE ....
