Question

The functions f(x) and g(x) are described below:

f(x) = 2x + 9
g(x) = 2x - 15

The graph of g(x) is obtained by shifting down the graph of f(x) by _____ units.

Answer 1

They both have the same slope m=2, so they are parallel lines...
the difference in y-intercepts is the vertical distance between them

Answer 2

so 24?

Answer 3

hello?
