Answer:
False.
Explanation:
If the institute in which you are enrolled have blackboard account for you then you are given a login ID and password which can be used to login onto the website.
But after logging in you are required to enter a separate password given by the instructor to begin the test.So we conclude that the answer to this question is False.
That would be a star network. A star network isn't necessarily shaped like a star, of course, but like you mention this topology has a central device, usually a server of some sorts, and then many different endpoints coming out of that central device, such as the client computers for the server.
Answer:
Yes, the relation is a function
Domain = {-3,1,3,7}
Range = {7,3,1-1}
Explanation:
Given
{(-3,7),(1,3),(3,1),(7,-1)}
To determine if the relation is a function or not, we check if every output has only one corresponding input.
The output are (7,3,1-1) while the input are (-3,1,3,7)
-3 ----;> 7
1 -------> 3
3 -------> 1
7 -------> -1
It is a function since every output only has one corresponding input
To find the domain, we look at the set of input values
Domain = {-3,1,3,7}
To find the range, we look at the set of output values
Range = {7,3,1-1}
