An injective function is not a function that is surjective. This means that you want a function that has a unique output for each input, that doesn't cover the natural numbers.
In formal terms a function [Math Processing Error] is injective if [Math Processing Error] implies [Math Processing Error].
We also know that it's not surjective because no value maps to [Math Processing Error] (or any odd number) since if [Math Processing Error], then [Math Processing Error]. However, since [Math Processing Error], the function isn't surjective.
Answer is B.

Answer:
no real solutions
3±32i
Step-by-step explanation:
used quadratic formula
Using the two given solutions and the general absolute value function we will get:
|x + 9| = 27
<h3>
Which absolute value function has that solution set?</h3>
The two solutions are:
x = 0 and x = -18.
Remember that the absolute value equation is something like:
|x - a| = b
If we want to have these solutions, then:
|0 - a| = b
|-18 -a| = b
From the first one, we have:
|-a| = b
Replacing that on the second equation we get:
|-18 -a| = |-a|
Notice that if we take a = -9, then we have:
|-18 + 9| = |+9|
|-9| = |+9|
This is true, so a = -9.
Then we find the value of b:
|18 + 9| = b = 27
Then the absolute value equation is:
|x + 9| = 27

Answer:
The scooter travels 15 feet in 1 second
The scooter travels 45 feet in 3 seconds
The scooter travels 60 feet in 4 seconds
The scooter travels 75 feet in 5 seconds
Step-by-step explanation:
First, let's find the number of feet the scooter travels in 1 second
(30 : 2) ÷ 2 = 15 : 1
Now that we have the unit rate, we can easily find the answers to the other questions.
(15 : 1) x 3 = 45 : 3
(15 : 1) x 4 = 60 : 4
(15 : 1) x 5 = 75 : 5
I Hope That This Helps! :)
