1.	Let `f(x)={(2x+a",",x ge -1),(bx^(2)+3",",x lt -1):}` and `g(x)={(x+4",",0 le x le 4),(-3x-2",",-2 lt x lt 0):}` `g(f(x))` is not defined ifA. `a in (10,oo), b in (5,oo)`B. `a in (4,10), b in (5,oo)`C. `a in (10,oo), b in (0,1)`D. `a in (4,10), b in (1, 5)`
Answer» Correct Answer - A `g(f(x))` is not defined if (i) `-2+a gt 8 and " (ii) "b+3 gt 8` `or a gt 10 and b gt 5`
