Question

Let fx=x3 be a function with domain {0, 1, 2, 3}. Then domain of f-1 is
(a) {3, 2, 1, 0}
(b) {0, −1, −2, −3}
(c) {0, 1, 8, 27}
(d) {0, −1, −8, −27}

Open in App
Solution

(c) {0, 1, 8, 27}


fx=x3Domain = 0, 1, 2, 3Range = 03, 13, 23, 33 = 0, 1, 8, 27So, f = 0, 0, 1, 1, 2, 8, 3, 27f-1 = 0, 0, 1, 1, 8, 2, 27, 3Domain of f-1 = 0, 1, 8, 27
