I was wondering if my work is correct. And that the continuity is (-inf, 3) but I don't know where to go from there

4. (20 pt) Consider the following function: C+ 3 h(x) = x24 3x 43 05 (a) (10 pt) Find lim, so h(x) if it exists (b) (10 pt) Find lim,-s h(x) if it exists (c) (10 pt) Find the intervals of continuity Continuity O: x+ 3 - 0+3-3 - * 2+34 +3 - 702 + 3 ( 0 ) + 3 = 3 I n() = 3 5: * +3X 43 -> 5 +3(5)+3= 25+15+3=43x X - 3 x + 1 - 5 - 3(5) + 1 = 25- 15 +1= 12X DNEX
