Which property is shown? 2*1=2

Mathematics
1 answer:
Dmitrij [34]3 years ago
4 0
The answer is C. 1 is considered the multiplicative identity because when you multiply it by a number, you get that same number as a product. similarly, 0 is considered the additive identity because adding 0 to anything returns the same number.

the distributive property would look more like 2(1+2) = 2(1) + 2(2)
associative property would be like 2*(3*4) = (2*3)*4
commutative would look like 2*1 = 1*2

F(x) = x2 - 5
Tcecarenko [31]

Answer:

D

Step-by-step explanation:

Given that f(x) has domain { 2, 4, 7 }

Substitute the values from the domain into f(x) for the range

f(2) = 2² - 5 = 4 - 5 = - 1

f(4) = 4² - 5 = 16 - 5 = 11

f(7) = 7² - 5 = 49 - 5 = 44

Thus the range is { - 1, 11, 44 } → D
