Which of the following is the parent function of all absolute value functions? f(x) = 3x f(x) = |x| f(x) = 2|x|

f(x) = |x|

Step-by-step explanation:

Absolute function is always represented by symbol | |

f(x) = 3x , f(x) is a linear function because we have 3x. there is no absolute sign. So it is not an absolute value function.

It has absolute value symbol. Also there is no other number multiplied or added inside or outside the absolute value symbol. So it is a parent function of all absolute value functions.

f(x) = 2|x| . It has absolute value symbol. But 2 is multiplied with |x| that make changes in the function f(x). So it cannot be a parent function.
