Answer:
A. 21
Step-by-step explanation:
To find range you just take the highest number and subtracted by the lowest
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.

Jason is buying 2 hats and 3 scarves for each of his 4 children
so he is actually buying 8 hats and 12 scarves.
a hat costs 8.50 and a scarf costs 5.50
so you put it into a equation
8.50(h)+5.50(s) = P h = hat, s = scarf, P = pay
8.50(8)+5.50(12) = P
68 + 66 = P
P = 134
hope this helps
The right answer is congruent and complementary because they both are different from each other and different causes
