Domain: x> 9 or (9,oo)x>9or(9,∞)
The range of yy is all of RR or (oo, oo)

Explanation:

y= log(x-9) . Domain: x-9>0 or x> 9 or (9,oo)

Range : As x approaches closer and closer to 9 from right, y gets more and more negative. So Range is all real numbers i.e (oo, oo) graph{log(x-9) [-40, 40, -20, 20]} [Ans]
