The domain and the range is [-6 to +inf)
Reducing the solution to a problem in lowest terms
Answer is B
Each number under the leaf side is the other half of the stem.
Therefore,
1 | 7 =1.7
1 | 3 =1.3
3 | 7 =3.7
So on and so forth.
Add
24+18=42
36^2+x^2=42^2
1024+x^2=1764
-1024 -1024
x^2=740
x=27.2
Since the sum of third side of a triangle is smaller than the sum of other two sides
So n<12+5
n<17
