Question 903319
The way those work is this:


Based on y=f(x),


y=f(x-h)  shifts h units to the right if h>0, or h units to the left if h<0.


y=f(x)+k  shifts k units up if k>0, or k units down if k<0.


For h and k both positive numbers,
y=f(x-h)+k  shifts h units to the right and k units up.
y=f(x-h)-k  shifts h units to the right and k units down.
y=f(x+h)+k  shifts h units to the left and k units up.
