Answer:
linear; translation up 4 units
Step-by-step explanation:
The given function is:
g(x) = x + 4
This is of the form:
y = mx + c
where m is the slope and c is the y-intercept
Therefore, g(x) is a linear function
The parent function is:
g(x) = x
g(x) = x + 4 means that the function is translated up 4 units
