Answer:
C. It is translated up 1 unit.
Step-by-step explanation:
Translations of a function f(x)
To translate a function f(x) a units to the right, we have f(x-a)
To translate a function f(x) a units to the left, we have f(x+a)
To translate a function f(x) a units up, we have f(x) + a
To translate a function f(x) a units down, we have f(x) - a
In this question:
g(x) = 5x + 1
f(x) = 5x
This means that the function g(x) is 1 added to the function f(x), that is, it is translated up 1 units, and the correct answer is given by option c.
