Step-by-step explanation:
To reflect a function about the vertical axis, just negate the variable.
For example, if we want to reflect this function
[tex] y = log(x) [/tex]
about the y axis or vertical axis, we just make the x negative
[tex]y = log( - x) [/tex]
Another example,
[tex]y = |x| [/tex]
To reflect about y axis or vertical axis,
[tex]y = | - x| [/tex]
So here l,the answer with negative variables are function that are reflected about the y axis.
The options are the first and the fifth option.
