1)
The given function is expressed as
f(x) = log2x + 4
where
2 is the base of the logarithm
The graph is shown below
If a function, f(x) is translated d units upwards, it becomes f(x) + d
For the given function, the parent function is f(x) = log2x where 2 is the base.
f(x) = log2x + 4 means that the parent function was translated or shifted by 4 units upwards
On the left, the graph gets close to x = 0 but it doesn't touch it. Thus,
Vertical asymptote is x = 0
