OpenStudy (phi):

in (a) , what does the -3 do ?

OpenStudy (adi3):

move the graph down

OpenStudy (phi):

by 3 steps

OpenStudy (adi3):

yes

OpenStudy (phi):

what does the +1 in (x+1) do ?

OpenStudy (adi3):

move it left by one

OpenStudy (phi):

it shifts the graph 1 step to the left.

OpenStudy (phi):

so in total, (a) shifts the curve down 3 and 1 to the left. (every point on the curve is moved down 3 and 1 to the left)

OpenStudy (adi3):

yes

OpenStudy (adi3):

so how will the graph look like

OpenStudy (phi):

pick a few points on the curve. move each point down 3 and to the left 1 then connect the dots.

OpenStudy (adi3):

(b)

OpenStudy (adi3):

(c) sorry

OpenStudy (phi):

(c) does: flip across the y-axis then shift left 1 step flip across the x-axis "squish down" by 1/2 (make the y value 1/2 its original) then shift the whole thing down 2 steps
