1. The problem statement, all variables and given/known data For f(x)=((x^(2)-2x-3)/(x-3)), restrict the domain of f(find Dom (f) first) so that Rnage(f)=(-2,4)U(4,11) 3. The attempt at a solution I found that when x=3, the function will be undefined. so the domain(f) should be (-infinity,3)U(3,+infinity). I GUESS now I should go to the equation again and factor the nomunator so that I get (x-3)(x+1)/(x-3). then f(x)= x+1. as the Range given above. I have to plug it in and solve for x, RIGHT? -2<x+1<11 -3<x<10 = the domain of f with te restriction that x is Not equal to 3. Is that right OR am I missing something?
