describe how the graph of y=f(-2x+6)+7 can be obtained from the graph of y=f(x)

now I'm just gonna double check here,correct me if I'm wrong

+6 would be the horizontal translation
+7 would be the vertical

I'm just a little confused about the -2 beside the x,what exactly does that mean?

If $f(x)=mx+c$

Both +6 and +7 are vertical translation.

-2:
The -ve sign will change its gradient to opposite sign gradient.
The 2 will increase its steepness.
