Hi, i need some help to solve this question,

First, what does it mean to "state the transformation"?

Second,can someone solve it and show me how he/she did it?

State the transformation applied toy= log_{5}xfor each of the following:

a)y= −log_{5}x

b)y= log_{5}(−x)

c)y= −log_{5}(−x)

Thank very much!
