4. Which of the following statements are true and which are false ? Justify your answers with a short proof or counter-example. 5x2=10 (a) If A and B are two subsets of a universal set U, then Ac \B = A\ Bc. (b) The roots of a quadratic equation are always real numbers. (c) lx+yl = lx1 + ly1 for all x,yE R. (d) The contrapositive of 'If two triangles have the same area, then they are congruent' is 'If two triangles are congruent, then they have the same area'.

Hi,i can’t upload attachment but the question says the graph of f(x)=square root -x+2 and h(x)= 2 to the power of x then -1.The graph of f(x) has a restricted domain.Then they drew a graph of these functions,now they ask: 1)For what values of x is h(x)=f(x)+3? 2)For what values of x is h(x) . f prime x smaller than and equal to 0? How do I do these questions,do I have to calculate or where do I start?Please help me,I’m very confused.Thanks
