    Take these functions:

    y=-f(x) with the coordinates (-1,-1)
    y=f(-x) with the coordinates (-1,-1)

    -f(x) is a reflection in the x direction so would I multiply the y coordinate by -1 to get my new point as (-1,1)?

    f(-x) is a reflection in the y direction so would I multiply the x coordinate by -1 to get my new point as (1,-1)?

    Thanks

    Yes

    This is because -f(x) reflects the graph in the x-axis, and f(-x) reflects the graph in the y-axis.
