(a)If `A={x in R:x^2-5x+6=0}` and `B={x in R:x^2=9}`,
` `find `AxxB`.

Let A={x in R,x^2-5x+6=0 and B={x:x in R,x^2=9} . Find (AuuB) and (AnnB)

Let A={x: x in R,x^2-5x+6=0} and B={x:x in R,x^2=9} Find A-B , B-A and verify that (A-B)uu(B-A)=(AuuB)-(AnnB) .

Let A={x: x in R,x^2-5x+6=0 } and B={x:x in R,x^2=9} Write A and B in roaster form.

Write the following as intervals i) {x: x in R,-4 lt x le 6} ii) {x: x in R,-12 lt x lt-10} iii) {x: x in R, 0 le x lt7} iv) {x: x in R, 3 le x le 4}

Consider the sets A and B given by A = {x:x is a natural number, 2lexle6 } B = {x:x is a prime number x le7 } C = {x : x^2-5x+ 6 = 0} Write A,B and C in the roster form.

A relation R is defined on the set Z of integers as follows. R ={ (x, y) in R: x^2+y^2=2 5} Express R and R^-1 as the sets of ordèred pairs and hence find their respective domains.

if the function f : R rarrR be defined by f(x) = x^2 + 5x + 9 find f^(-1)(9).
