1.	If f is a function defined from R to R, is given by f(x) = x^2 then f ^-1(x) is given by?(a) 1/(3x-5)(b) (x+5)/3(c) does not exist since it is not a bijection(d) none of the mentionedI got this question during an interview for a job.Question is from Inverse of a Function in portion Basic Structures: Sets, Functions, Sequences, Sums and Matrices of Discrete Mathematics
Answer» The CORRECT option is (c) does not exist SINCE it is not a bijection To explain: It is not a ONE one FUNCTION HENCE Inverse does not exist.
