Which statement correctly describes the relationship between the graph of f (x) and the graph of g (x) = f (x) - 1?

g (x) is the graph of f (x) translated 1 unit down, parallel to the y-axis

given f (x) then f (x) ± c

translates f (x) by c units vertically up if c is positive and

translates f (x) by c units vertically down if c is negative

here f (x) - 1 ← move down vertically by 1 unit
