Write "True" if the statement is correct or "False" if the statement is incorrect on the space provided. 1. If R is a relation, then the domain of R-1 = Range of R and Range of R-1 = Domain of R. 2. Given a relation R, the inverse of R is given by R-1 = {(x, y): (x, y) = R}. P(x) Q(x) 3. The domain of a rational function f(x) = q(x) is not zero. 4. The diagonal matrix where all the elements of the diagonal are 1 is called identity matrix. 5. If A = a11 ( is the set of all real numbers such that a12 a22 ), then det(A) = a₁2921 - 911922.​
