Question

Determine whether or not the given function is one-to-one and if so, find the inverse. If f(x) = (4x + 2)* has an inverse, give the domain of f-1. a) Of c) = (2 - 4x)1/4; domain: 2) 2 - 1/4 b) O f-1(2) = domain: (0,0) 4 c) Not one-to-one d) Of () 1/4 - 2 -; domain: (-0,0) 4 e) Of (2) = 2-1/4 -; domain: 4 (1:0) Question 4 Determine whether or not the given function is one-to-one and, if so, find the inverse. If f(x) = (6 + 3 z2)? has an inverse, give the domain of f 1 a) Of(0) = 1/2 ; domain: (-0,0) b) o f-1() = (6 + 322)^/?; domain: (0)

Answer 1

we are supposed to answer only first question
