Question

What is the
domain of the
function?
g(u) = 1/ (1+(1/u))​

Answer 1

Answer:

given function is =====> 1/(1+(1/u))

on cross multiplying in denominator and arranging ...

we get u/u+1

now the domain means the numbers which you can give to the variable u .

here the denominator cannot be zero.

there fore u+1 not equal to zero ===> u not equals -1 .

there fore domain will be R - {-1}

WHERE R IS THE SET OF ALL REAL NUMBERS
