Step-by-step explanation:
There are many examples. The simplest is
1 -

It is trivial that

2 -

That function is injective as well.

An example of a function that is NOT injective is

Notice that

Answer:
f= (x-4, y+6) or f= (x-4),(y+6)
Step-by-step explanation:
* when you move to the left you are subtracting from x because eventually you'll get to the negatives, if you were going to the right you would add
* going up from y, you would be adding since the further up you go the higher positive number you'll get, if you were going down it would be subtracting from y
167.462 is the bigger number
Answer:
a = 8
Step-by-step explanation:
x-1 = 0
x = 1
let x³ + ax² -x -8 be p(x)
hence, p(1) = (1)³ + a(1)² -1 -8 = 0 (since, x-1 is a factor)
= 1 + a - 1-8
= a - 8 = 0
therefore, a = 8
