The domain is the set of all possible x values:

The range is the set of all possible y values:

The relation is a function, because you're associating one y value for each x value (i.e. you're not mapping twice the same x value)
Diametre = 2 x Radius
Radius = 7
Circumference = 2πr
= 2x22/7x7
= 44
Answer:
Mean
Step-by-step explanation:
The mean is the average so practically meaning most in this case.
Not muslim but felt like I could help
I see you're probably trying to use a math editor to present this problem. Unfortunately, I'm unsure how to decipher your "-\frac {a }{8.06)." What fraction are you speaking of?
Given "<span>#-\frac { a } { 8.06} + 7.02= 18.4#," all I can say with certainty is that you could legitimately subtract 7.02 from both sides:
</span><span>#-\frac { a } { 8.06} + 7.02= 18.4#
- 7.02 = -7.02
After I've heard back from you, I'll try to help you solve the entire problem.

Answer:

Step-by-step explanation:
<u>Given polynomial </u><u>function </u>:-

<u>To </u><u>find</u> :-

<u>Solution:-</u>

Here, the value of x is 7(given).
So, <u>Substitute the value of x on the RHS and </u><u>on </u><u>LHS </u>:-

Simplify the RHS:-
<u>Multiply 10 and 7 :-</u>


<u>Add 70 and 45 :-</u>

We're done!
Hence, the value of f(7) would be,
