What transformations produce the graph of g(x)=- | 3x | from the graph of the parent function f(x)=|x| select all that apply

 This is a compression  by a factor of 3 in the x direction

(horizontal compression by factor of 3)

This reflects it about the x axis

Step-by-step explanation:

f(x)=|x|

h(x) = |3x|

 This is a compression  by a factor of 3 in the x direction

g(x) =-|3x|

This reflects it about the x axis

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
