Is this a function or not

Yes

Step-by-step explanation:

For a relation to be a function it must have an individual x value for every y. Since the x-values never repeat this is a function. An easy way to tell this on a graph is the vertical line test if you can draw a vertical line anywhere on the graph and have it only intersect with the relation once then it is a function.

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

=
