Given:
x is a number between 8 and 12 exclusive.
To find:
The value of x.
Solution:
It is given that x is a number between 8 and 12 exclusive. It means the value of x lies between 8 and 12 but 8 and 12 are not included.
The whole numbers for range are 9, 10, 11.
Therefore, the values of x are 9, 10, 11 and the value of x in the form of inequality is .
Answer:
Check below
Step-by-step explanation:
1. Definition for intervals
2. Functions
1)
Let's perform graph tests.
That's an one to one, injective function. Look how any horizontal line touches that only once. Also, It's a surjective and a bijective one.
2)
Injective, surjective and bijective.
Injective: a horizontal line crosses the graph in one point.
3)
The cosine function is not injective, bijective nor surjective.
4)
Since e, is euler number it's a constant. It's also injective, surjective and bijective.
5) Quite unclear format
Despite the Restriction for the CoDomain, the function remains injective, surjective and therefore bijective.
Not injective nor surjective therefore not bijective too.
Injective (one to one), Surjective, and Bijective.
Surjective.
Surjective
12.f: US Citizens→Z, f(x) = the SSN of x.
General function
13.f: US Zip Codes→US States, f(x) = The state that x belongs to.
Surjective
