Question

what is the graph of y= arccos(x-2)
vii
find the grahp of cos(x-2) first and then switch your x and y value, oh another thing with arc cos you have to limit it from one point to another or else its not a function anymore, so say a regular cos has 2pi for its period don't graph that whole 2pi for the arccos graph one pi only i don't know if im makign sense or not
