Question

Express the following functions as set of ordered pairs and determine their range.
f:X->R,f{x) = x3 + 1, where X= {-1,0, 3, 9, 6}​

Answer 1

Answer:

We have, f : X→ R,f(x) = x3 + 1. Where X = {-1, 0, 3, 9, 7} Now f (-l) = (-l)3 +1 =-l + 1 =0 f(0) = (0)3 +l=0+l = l f(3) = (3)3 + 1 = 27 + 1 = 28 f(9) = (9)3 + 1 = 729 + 1 = 730 f(7) = (7)3 + 1 = 343 + 1 = 344 f= {(-1, 0), (0, 1), (3, 28), (9, 730), (7, 344)} Range of f= {0, 1, 28, 730, 344}Read more on Sarthaks.com - https://www.sarthaks.com/113467/express-the-following-functions-as-set-of-ordered-pairs-and-determine-their-range
