Answer:

To do this, you imagine a vertical (up and down) line moving across your graph from left to right. It should only be touching the line at one point at a time. If it is touching more than one point on the line at a time, the line is not a valid function. The first line and its inverse both pass the test.

Which expressions are equivalent to x+x+x+2

Nikolay [14]

Answer:

A and D

Step-by-step explanation:

x+x+x+2=3x+2

A does work because 3x+2=3x+2 (I think A might've been a typo)

B doesn't work because the coefficients are switched

C doesn't work because that's 3x+6

D does work because that evaluates to 2x+2+x=3x+2

E doesn't work because it's not 3x+2x
