The domain is the set from which the function "starts", i.e. it is the set of the inputs you feed the function with.
In this case, the function starts from the set 
and lands on the set 
So, the domain is the set .
When you rewrite the exhumation. After substituting the given value it should look like 15-4(3). Solve for parenthesis first(meaning to multiply) -4 times 3 is going to equal -12. Then you subtract 15-12 and you will get the answer if 3
For simple integer factors as this one has, you want to find two values for the quadratic in the form ax^2+bx+c. Let the two values be j and k. These two values must satisfy two conditions.
jk=ac=10 and j+k=b=11, so j and k must be 1 and 10.
Now replace bx with jx and kx...
2x^2+x+10x+5 now factor 1st and 2nd pair of terms.
x(2x+1)+5(2x+1)
(x+5)(2x+1)
9/5 or 1 & 4/5 is the answer
