Let f:N→R such that `f(x)=(2x−1)/2` and g:Q→R such that `g(x)=x+2` be two function. Then `(gof)( 3/2)` =?

Text Solution

Verified by Experts

The range of `f(x)` for which `g(f(x))` is defined is `{3,4}`.
Hence, the domain of `g{f(x)}` has two elements.
Therefore, the range of `g(f(x))` also has two elements.
