3)

For cach of the following functions, state whether they arc onto or not. (You must enter T or F -- True and False will not work.) f : (-infinity, 0] rightarrow (0, 1],f(x)=1/x2+1 f : (-infinity, 0] rightarrow R,f(x)=x3 f : R-{0} rightarrow R,f(x)=1/x2 f:R rightarrow R,f(x)=x2 f : [7, infinity) rightarrow R,f(x)=x2 Consider the function Find the inverse of f f-1(x)= The domain of f is { x|x The domain of f-1 is{ x|x The range of f is { y|y The range of f-1 is { yy Consider the function f(x)=1/6x-3 Find the inverse of f f-1(x)= The domain of f is { x|x The domain of f-1 is{ x|x The range of f is { y|y The range of f-1 is { yy
