Answer:
Domain
and Range
Step-by-step explanation:
Let 
be the given function
Function:
Function can be defined as "A special relationship where each input has a single output".
It is often written as "" where x is the input value.
Domain:
The domain of a function is the complete set of possible values of the independent variable.
Range:
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.
Function is the set of all ordered pairs of domain and range. It can be written as
where 
are domain and 
are range
Given the ordered pairs of domain and range 
where 
are domain and 
are range.
ie, Domain 
and Range 
X^2 + 6^2 = {sqrt (117)}^2
x^2 + 36 = 117
Solve for x.
x^2 = 81
x = 9
Answer:
x=-29
Step-by-step explanation:
Minus 17 from both sides.
So x=-29
In mathematics, a radical expression is defined as any expression containing a radical (√) symbol - includes square roots, cube roots and so forth. Expressing in simplest radical form just means simplifying a radical so that there are no more square roots, cube roots, 4th roots, etc left to find.
So √12 is in radical form. I think what you are asking for is to reduce the expression to its simplest radical form.
So 12 = 4*3, √12 = √4 * √3.
We can ‘reduce’ this by noting that √4 =2, so the expression becomes 2√3.
This cannot be further reduced because 3 isn’t a square or divisible by a square, so 2√3 is the simplest radical form.
