thankyou

x is bad and opposite,hence the big cross---NOT NORMAL

e.G. IF IT SAYS +2,YOU ACTUALLY -2...X is pretty messed up!!AND STUFF INDSIDE THE BARCKETS IS TO DO WITH X...(fx+2)

NUMBER OUTSIDE THE BRACKETS ARE TO DO WITH Y,THEY ARE CORRECT SO IF IT SAYS +2 ,IT IS PLUS 2

lol i hope this helped:)--it helped me....

there are 4 main graph transformations,

outside- f(x)+a

outside- af(x)

inside- f(x+a)

inside- f(ax)

if the a is on the inside of the bracket then it is to do with the  x(either moves or streches)

if the a is on the outside of the bracket then it is to do with the y (either moves or streches)

and if it has a '+/-' the whole thing moves up or down or sideways

and if it just is multiplied by so 'a' it streches/squishes

x is bad so you go opposite so if it is + you move left and - you move right

y is good so you just move normal.

hope this makes sense! this was influenced by anonymous, thankyou!

We got taught 8 of them :/ there's f(x)+a, f(x+a), -f(x), f(-x), af(x), 1/a f(x), f(ax) and f(1/a x) but I don't know whether to learn them all or not?
