Answer:

D

Step-by-step explanation:

4x²= 32

x²= 32 ÷4 <em>(</em><em>÷</em><em>4</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>

x²= 8

x= ±√8 <em>(</em><em>square</em><em> </em><em>root</em><em> </em><em>bith</em><em> </em><em>sides</em><em>)</em>

☆ A '±' symbol has to be added whenever we introduce a square root as the square of any number, positive or negative, would result in a positive number.

Note that mailing address is unique, but houses are not, meaning that you can't have house A and house B both referencing the same address.

So, in order to have a valid function, any two points on the function cannot have the same x value that lands on different y.

With this property mentioned, it's clear to see that
(house, address) is NOT a function; however, (address, house) is a function, since same x lands on multiple y values is a valid onto function. (a house that have multiple addresses)

Which graph models the equation 4x + 2y = 8?
yan [13]
The graph slanted from left to right.

4x + 2y = 8
-4x
2y=8-4x

divide the equation by 2 since you only need on y. -2x+8 =y

it's a negative x so the graph would be from upper left to lower right.
