Answer:
It's the first option.
Step-by-step explanation:
y = cos x transformed  to cos (x - π/2) moves  the graph  π/2 units to the right.
Multiplying by 3 to give 3 cos(x -  π/2)  stretches the graph 3 units parallel to the y-axis and adding 3 to this moves the graph up 3 units. 
So the required equation is y =  3(cos x -  π/2) + 3.

Answer:

Step-by-step explanation:
A linear equation is written as  , "m" being the slope and "b" being the y-intercept.
, "m" being the slope and "b" being the y-intercept.
The slope is how many times you rise/run in order to get from one point on the line to the next. You rise (go up/down) 1 unit and run (go left/right) 3 units. Plug in the numbers and you get 1/3.
The y-intercept is where the graph lands on the y-axis, which is 4.
