Practice CBSE Class 11 (Science) Relations & Functions — Cartesian Product, Relations, Domain/Range/Codomain, Functions and their Graphs in the app →If two ordered pairs (a, b) and (c, d) are equal, then:If n(A) = p and n(B) = q, then n(A × B) equals:A relation R from set A to set B is, by definition:If (x + 1, y - 2) = (3, 1), find x and y.Let A = {1, 2, 3} and B = {3, 4}. Find n(A × B):Let A = {1, 2} and B = {3, 4}. The total number of relations from A to B is:If A × B = {(p, q), (p, r), (m, q), (m, r)}, then A and B are:The Cartesian product A × A has 9 elements, two of which are (-1, 0) and (0, 1). The set A is:A relation R is defined on A = {1, 2, 3, 4, 6} by R = {(a, b): b is exactly divisible by a; a, b ∈ A}. The domIdentify the function h(x) = x^(2/3) + 2x. Which of the following is INCORRECT?Let A = {1, 2} and B = {3, 4}. The number of subsets of A × B is:R = {(x, x^3) : x is a prime number less than 10} in roster form is:Let A = {x, y, z} and B = {1, 2}. The number of relations from A to B is:
