which of the following functions shows the linear parent function, f(x)=x, shifted up?

Answer:
B
Step-by-step explanation:
If we have a general function g(x) = x, the transformations on this can be as follows:
[note a, b are constants]
From the 3 transformation rules, we can see that if we "ADD" a number to the function f(x) = x, we will get shifting UPWARDS.
From the answer choices, we can thus say that B is correct.
G(x) = x + 8
