How is the graph of y=-1/3x related to its parent function y=1/x a. it is horizontally stretched by a factor of 3 and reflected over the x-axis. b. it is horizontally stretched by a factor of 3 and reflected over the y-axis. c. it is horizontally compressed by a factor of 3 and reflected over the x-axis. d. it is horizontally compressed by a factor of 3 and reflected over the y-axis.

OPTION C.

Step-by-step explanation:

Some tranformations for a function f(x):

If , and , then the function is vertically compressed by a factor of "b".

If , and , then the function is vertically stretched by a factor  of "b".

If , and , then the function is horizontally compressed by a factor of "b".

If , and , then the function is horizontally stretched by a factor  of "b"

If , then the function is reflected over the x-axis.

If , then the function is reflected over the y-axis.

Given the function and the parent function , you can observe that:

The function is the function but horizontally compressed by a factor of 3 and reflected over the x-axis.
