1. domain is find by checking if function is defined on the points or not, for example log is defined only for positive real numbers, while sinx and cosx are defined for all real numbers.
2. once domain is found, range can be calculated by putting end limits of domain, or by finding minimum and maximum value of function withing this domain.
