Plz help idk how to do this

x = 5

Step-by-step explanation:

2x + 22 = 4(x + 3)

2x + 22 = 4x + 12

-2x = -10

x = 5

If you need some clarity on how I did this, let me know!

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
