Iwill mark the question is in the picture!

The highest peak is in the middle and both sides of it are fairly similar, so this would be a bell shaped distribution.

is only a line? i think so

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

see the picture for the graph.
