using the graph, choose the correct formula for the function g. a) g(x) = f(x) + 1b) g(x) = f(x) - 3c) g(x) = f(x + 1)d) g(x) = f(x - 3)

The graph scale is 0.5.
g(x) is 3 units lower than f(x). How do we find this?
A isn't correct because then g(x) would be 1 above f(x).
C isn't correct either because that would mean that g(x) is f(x) moved 1 over to the left.
D isn't correct because that would mean g(x) is f(x) moved 3 to the right.
B is correct because it means that g(x) is f(x) moved down 3 units.
I got B, but it is always helpful to double check work. Hope this helps!
