Question 945421
1. what is the domain of f (x) = x^2-14x+48/x-8
Domain:: All Real Numbers except x = 8
------------------------------
 2. What is the domain of F(x)= Square root (5-10x)
Solve:: 5-10x >= 0
10x <= 5
x <= 1/2
Domain:: All Real Numbers <= 1/2
------------------------------------------
 3. What is the domain of f(x)= x-9/x^2+6x+9
Solve:: x^2 + 6x + 9 = 0
(x+3)^2 = 0
x = -3
Domain:: All Real Numbers except x = -3
===========
