Given:
The given function is:
To find:
The value of x that is in the domain.
Solution:
Domain is the set of input values.
We have,
We know that the square root is defined for non negative values. So,
Thus, the domain of the given function is all real number that are greater than or equal to 7.
In the given options 0, -3, 6 are less than 7 but 8 in option A is the only value that is greater than 7. So, 
is in the domain of the given function.
Therefore, the correct option is A.
The answer should be B.
5(6.86x)
There are many sets of numbers that add up to 97. Here are just three sets of them. :) 7 + 90, 23 + 73, and 13 + 84
Answer:
A) (4, 8)
General Formulas and Concepts:
<u>Algebra I</u>
- Functions
- Vertical Line Test - The function must have only one y-value per x-value
Step-by-step explanation:
<u>Step 1: Define</u>
Relation {(4, -5), (-3, -2), (5, -2), (1, 7), (4, 8)}
<u>Step 2: Identify</u>
When we apply the Vertical Line Test, we see that we have an error at x = 4. Therefore, this relation is not yet a function.
We can see that if we remove either (4, -5) or (4, 8), the relation would then pass the Vertical Line Test and become a function.
Therefore, our answer is A) (4, 8)
