3
Which is the equation of the blue curve? (Hint: the red curve is y=sinx)
y=3sinx+2
y=3sin(x+2)
y=2sinx+3
y=5sinx
4
What is the equation of this graph?
y=-cosx+2
y=sin(x+π/2)+2

y=sin(x-π/2)+2
5
State the equation of the blue curve (the red curve is y=sin x).
y=sin(x/3)
y=sin(x)/3
y=3sin(x)
y=sin(3x)
6
What is/are the transformation(s) from y=cosx to the graph shown?
Translation +1 in y direction
Stretch in y sf -1, then translation +2 in y
Stretch in x sf -1, then translation +1 in x
Stretch in x sf -1, then translation +1 in y
7
State the transformation from the red curve to the blue curve.
Horizontal translation to the right by π/3 units
