Finding Domain & Range
Domain Rules
- Denominator cannot be zero
- Expression under even root must be non-negative
- Logarithm argument must be positive
- Polynomial functions: all real numbers
Range Determination
- Consider behavior at endpoints and asymptotes
- Find critical points (derivatives = 0)
- Analyze function as x approaches infinity
- Consider any horizontal asymptotes
