<h2>
Answer:</h2>
<em>Domain:</em> (−∞,∞) , {x|x∈R}
<h2>
explanation:</h2>
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

i hope this helped. please give brainliest if it did!
<h2>Determining if a Relation is a Function or not</h2><h3>
Answer:</h3>
1: Function
2: Not a Function
<h3>
Step-by-step explanation:</h3>
We consider a Relation to be a Function if one input from the Domain corresponds to only one output from the Range or multiple inputs from the Domain corresponds to only one output from the Range.
Part 1:
Given:
![&\text{Domain} &\text{Range} \\ &- 5 &8 \\ &-2 &-10 \\ &0 &8 \\ &6 &15](https://tex.z-dn.net/?f=%26%5Ctext%7BDomain%7D%20%26%5Ctext%7BRange%7D%20%5C%5C%20%26-%205%20%268%20%5C%5C%20%26-2%20%26-10%20%5C%5C%20%260%20%268%20%5C%5C%20%266%20%2615)
We can see from the given table that there's no input from the Domain that corresponds to multiple outputs from the Range. We can only see multiple inputs,
and
from the Domain that corresponds to only one same output from the Range,
. So, we consider this relation a function.
Part 2:
<em>Please</em><em> refer</em><em> to</em><em> the</em><em> </em><em>image</em><em> </em><em>for</em><em> the</em><em> </em><em>Given</em><em> </em><em>Graph</em><em>.</em>
If we consider
to be Domain and
to be Range, we can see for the same input,
, it corresponds to <em><u>infinite</u></em> outputs. Other way of view this is that consider the point
, no matter what real values of the output,
, the point will still be on the line. So, this graph is not a function.
Answer:
$5400
$45
Step-by-step explanation:
Interest = principal x interest rate x time
principal = p
interest rate = 15%
time = 20/365 = 0.054795
Interest = 5445 - p
5445 - p = 0.15 x p x 0.054795
5445 - p = 0.008219p
Collect like terms and solve for p
p = $5400
Interest = 5445 - 5400 = $45
Slope intercept form = Y = Mx + B
15 = -3y + 21x
3y = 21x - 15
Y = 21/3 X - 15/3
Y = 7x - 5 = SI Form
