Answer:
The statement
is a tautology.
Step-by-step explanation:
We have the following statement 
A truth table shows how the truth or falsity of a compound statement depends on the truth or falsity of the simple statements from which it's constructed.
The simple statements from the statement given are:
,
,
,
, and
with these you can construct the following truth table.
A tautology is a formula that is always true, it is true for every assignment of truth values to its simple components.
The last column contains only true values. Therefore, the statement is a tautology.

Step-by-step explanation:
Number two is proportional just do Y over X y/x meaning divided all the y’s over the x’s so 25 divided by 5 30 divided by 6 35/7 40/8 they all equal 5 so it’s proportional
number three isn’t proportional when you do y/x they all come out differently so you do y2-y1 over x2-x1 16-4/4-2 16-4=12 4-2=2 then you divided 12/2 that equals 6 you do that again but with the next numbers but they don’t equal so it’s no equation no constant
Answer:
Yes, this is a function.
Step-by-step explanation:
This is a function because every input goes to exactly one output. Although 1 is listed twice in this example, it still goes to the same output of 15.
