Domain of { (1,x),(2,y),(3,x),(4,z)}is

Let A={1,2,3,4} and B={x,y,z}. Let R:A rarr B is defined as R={(1,x),(1,z),(3,x),(4,y)} then find domain and range of R .

Let A = {1, 2, 3, 4} and B = {x,y,z}. Let R be a relation from A into B defined by : R= {(1,x), (1,z), (3,x), (4,y)}. Find the domain and range of R.

The domain of y=cos ^(-1)(x^(2)-4) is

If [(1,3,3),(1,4,4),(1,3,4)][(x),(y),(z)]=[(1),(2),(-3)], then the values of x, y and z respectively are

If R ={ (x,y) : x,y in z, x^(2) +y^(2) le 4 } is a relation on Z Z then domain of R is { 0,-1,k,-2,2} find the value of k.

Find the domain of y=sin^(-1)[(4)/(3+2cos x)]
