y=(x^2+8x+12)/∜(x+5)
Domain: What values are permitted for x?
The numerator makes no restrictions. Polynomials can accept all real numbers.
The denominator puts a retriction on being fourth-root function, since that can only accept expressions which are greater than or equal to zero.
You MUST have x+5>=0
The domain is, the real numbers greater than or equal to negative 5.
