If A={-2,-1,1,2} and `f={(x,1/x):x}` Find :Is f a function?

A = {- 2,-1, 1, 2}, f= {(x, 1/x ):x in A} . List the domain and range of f

If f(x) is a polynomial of degree 2 such that f(0) = 1,f(1) = 0 and f(3) = 5, find the domain of the function f such that f (x) is never negative.

Let f{(x,(x^2)/(1+x^2):x in R} be a function from R into R.Determine the range of f.

If f(x)=-x^(2) , find f^(-1)({9,-36}) .

If f : [-1,1] rarr R, f(x)=x/(x+2) , show that f is one-one and find the inverseof f : [-1,1] rarr range of f.

If f(x)={(2x-1, xle0 ),(x+1,0ltxlt2),(4-5x, xge2)} find f(0),f(-1),f(1),f(2),f(4).

If f:RrarrR defined by f(x)=(3x+5)/2 is an invertible function, then find f^(-1)

Find f {f (x)} if f(x)=(x+1)/(x-1)
