Can someone show me how to do this problem: find the domain and write the set notation

Step-by-step explanation:

To find the domain of a rational expression like you need to find out where the denominator is 0 because you cannot divide by 0

So, take the denominator x - 3 and set it to zero and solve for x

x - 3 = 0

x = 3

So the domain is all real numbers but where x = 3. You can write this in a few different ways in set notation.

NOTE

R = real numbers

= element of

| = such that

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25
