Determine the functions f: R -> R are onto, f(x) = |x| + x
Let A = {1, 2, 3, 4} and B = {0, 3, 6, 8, 12, 15}. Consider a rule f (x) = x² - 1, x∈A, then show that f is a mapping from A to B.
The following sets have been defined using the | notation. Re-write them by listing some of the elements.
i. {p | p is a capital city, p is in Europe}
ii. {z | 3z = n2, z and n are natural numbers}
