Answer:
The domain is 
The range is 
Step-by-step explanation:
we have

<em>Find the domain</em>
Remember that
The domain of a function is the set of all possible values of x
we know that the radicand of the function must be greater than or equal to zero
so

solve for x

therefore
The domain is 
<em>Find the range</em>
Remember that
The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.
For x=7
The value of y is equal to

so
The solution for y is the interval [1,∞)
therefore
The range is 
Opposite Numbers and their Sums:
1+6=7
2+7=9
3+8=11
4+9=13
5+10=15
Because of this, the pair of opposite numbers are 3 and 8 if you want the pair that equal 11.

20 watches are made since 385 = 15n + 85. 385 - 85 is 300 and 300 divides by 15 is 20.
