Question: The function 
has a range of 
.
What is the domain?
Domain: 
Step-by-step explanation:
Domain is the input, and range is the output. In other words, the domain is the 
value, and the range is the 
(the whole value, output). So we will solve each one step by step, all with the same solution. To reiterate, what is done for -7, for instance, will be done for every other range.
Start with -7. Remember, solve this accordingly.
Replace the with the range
Solve
<em>(When adding negative a to a positive, it results in a negative.)</em>
That's how you solve it.
Answer:
See below
Step-by-step explanation:
sqrt(x^2+81)=x+10
x^2+81=x^2+20x+100 (which is one of the options)
81=20x+100
-19=20x
x=-19/20
So there's the work done.
10 - 2 = 8
Biggest number subtracted by the smallest number is range.
