The equivalent expression
We have:

Expand

Apply laws of indices

The interval notation is 
Explanation:
The inequality is 
Let us complete the square, we get,

Simplifying, we have,


Adding both sides of the equation by 11, we get,

Since, we know that for
, if n is even then ![-\sqrt[n]{a}](https://tex.z-dn.net/?f=-%5Csqrt%5Bn%5D%7Ba%7D%3Cu%3C%5Csqrt%5Bn%5D%7Ba%7D)
Thus, writing the above expression in this form, we get,

Also, if
then
and 
Then ,we have,
and 
Solving the inequalities, we get,
and 
Merging the intervals, we have,

Hence, writing the solution in interval notation, we have,

Therefore, the answer is 
The Function models Jay's total monthly salary s(x) in dollars would be s(x) = 0.03s - 1060.
<h3>What is a function?</h3>
A function is a type of relation, or rule, that maps one input to a specific single output.
Given
Base salary = $2500 per month
Commision = 3% on Sales over 48000
Determine the function s(x) for sales over $48000
Let's Represent the total sales in a month with s.
So, the function s(x) is:
s(x) = Base Amount + Commission x Sales over $48000
s(x) = 2500 + 3% (s - 48000)
s(x) = 2500 + 0.03(s - 48000)
s(x) = 2500 + 0.03s - 1440
s(x) = 0.03s - 1060
Hence, the Function models Jay's total monthly salary s(x) in dollars would be s(x) = 0.03s - 1060.
