Question

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

A. The graph of g(x) is the graph of f(x) translated 1 unit right

B. The graph of g(x) is the graph of f(x) translated 1 unit down

C. The graph of g(x) is the graph of f(x) translated 1 unit left

D. The graph of g(x) is the graph of f(x) translated 1 unit up

Answer 1

Option B. The graph of g(x) is the graph of f(x) translated 1 unit down

Explanation:

we know that

g(x)=f(x)-1

so

The rule of the transformation is equal to

f(x) -----> g(x)

(x,y) -----> (x,y-1)

That means ----> The translation is 1 unit down
