1. What effect does replacing x with x -4 have on the graph for the function f(x)?
f(x)= |x|-5
A vertical shift of 4 up.
A horizontal shift of 4 to the right.
A vertical shift of 5 down.
A horizontal shift of 4 to the left.
Question 4

Sagot :

Answer: Choice B

A horizontal shift of 4 to the right.

========================================================

Reason:

Replacing x with x-4 basically means we're decreasing each input by 4 units.

What this does is move the xy axis 4 units to the left. If we held the function curve fixed in place as the xy axis moved like this, then it would give the illusion the function is moving 4 units to the right.
