What is the effect on the graph of the parent function f(x) = x when f(x) is replaced with f(x) - 4? a) shifts the line 4 units up b) shifts the line 4 units down c) increases the slope of the line by a factor of 4 d) decreases the slope of the line by a factor of 4

  B) shifts the line 4 units down

Step-by-step explanation:

The point (x, f(x)) is moved to the point (x, f(x)-4), one with a y-coordinate 4 units lower. The line is shifted down 4 units.

B) shifts the line 4 units down.

Step-by-step explanation:

The constant negative number makes a vertical translation of the parent function in the -y direction. Slope keeps intact. So, the right answer is B.

answer is:
