Question

Which equation describes the relationship of the graphs of f(x) and g(x)?

Answer 1

Answer:

Depends on which function is which...

Step-by-step explanation:

The blue graph is the same as the yellow graph but raised up 1 unit. That means either:

blue function rule = yellow function rule + 1

or

yellow function rule = blue function rule - 1

Your picture doesn't say which function is  f  and which is g.

If, just to pick a possibility, the blue function is g(x), then

g(x) = f(x) + 1

If the blue function is f(x), then

g(x) = f(x) - 1
