What can you say about the end behavior of the function f (x) = log2 (4x+8) + 16

One end increases and one end decreases

Both ends increase

Both ends decrease

Or one end decreases and one end approaches a constant

From left side it will increase

and it also increases on the right

The second choice is correct

One end increases and one end decreases because log2=0.3 and if you multiply that by the leading coefficient, 4, you will get 1.2. Because the new leading coefficient, 1.2, is positive, one end goes up and another end goes down.
