is this a function?

No.

Step-by-step explanation:

In a function, each x only has one y value.

Each x-value has 2 y-values.

For example, for x=2, its y can be BOTH 2 and 4.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
