**Paragraph for Question Nos. 4 to 6** is said to be well behaved if it lies in interval [0, 2 ] . They are intelligent if they make domain of f + g and g equal. The values of for which h( ) is defined are handsome. Let f(x) = x^2 - 2( ^2 - 3)x - 12 , g(x) = (x^2 - 49),h( ) = [ ₀^ 4 ^2 t , dt - ^2 ] , where is in radians. Complete set of values of which are intelligent is :
