Write the domain of the following real functions
`f(x)=(2x+1)/(x-9)`

Text Solution

Verified by Experts

The correct Answer is:
(i) Domain is x `in` [ R - {9}]
(ii) p(x) is defined for all values of x. so domain is x `in` R.
(iii) Domain x `in` (2,`alpha`)
(iv) for all values of x, h(x) is defined . Hence domain is x `in` R.
