When given a graph, the vertical line test can be used to determine functionally. describe the vertical line test and explain the reasons why a graph would, or would not, represent a function

The vertical line test is where you take a pencil or any vertical object and you move it across a function. If that vertical line intersects a graph more than once it would not be a function because for it to be a function it has to have one input value and one output value.

(Hopefully this helps!!)

Step-by-step explanation:

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
