Provide the missing information 8 A function is a function t
     Provide the missing information. 8) A  function is a function that can be written in the form f(x) = P(x)/q(x) where P(x) and q(x) are polynomials, and q(x) notequalto 0. Write the domain in interval notation. 9) f(x) = x^2 - 9/x + 3 
  
  Solution
8)
 rational function
9)
 f(x) = (x^2+9)/(x+3)
denominator must not be 0
 x+3 !=0
 x = -3
 domal = r - {-3}
