Find the domain and range of the function f(x)= 1/ 2x+1 Share with your friends Share 1 Manbar Singh answered this We have,fx = 12x+1Clearly fx is not defined when 2x+1 = 0 i.e. when x = -12So, domain of f = R--12Now, y = 12x+1⇒x = 1-y2yClearly x is not defined when y = 0So, range of f = R-0So, domf = R--12 and rangef = R-0 -1 View Full Answer Sanjay Aravindhan answered this domain : x ∈ R-{-1/2} range : R-{0} 1
