Plz asap! which set of transformations is needed to graph f(x) = –2sin(x) + 3 from the parent sine function? a. vertical compression by a factor of 2, vertical translation 3 units up, reflection across the y-axis b. vertical compression by a factor of 2, vertical translation 3 units down, reflection across the x-axis c. reflection across the x-axis, vertical stretching by a factor of 2, vertical translation 3 units up d. reflection across the y-axis, vertical stretching by a factor of 2, vertical translation 3 units down

The main function is given by:
 f (x) = sine (x)
 We then have the following transformations:

 Reflections:
 Reflection or turning is the mirror image of a figure. It can also be said that it is the turning of points and graphs around the axes.
 To graph y = -f (x), reflect the graph of y = f (x) on the x-axis. (Vertical reflection)
 f (x) = - sine (x)

 Expansions and vertical compressions:
 To graph y = a*f (x)
 If a> 1, the graph of y = f (x) is expanded vertically by a factor a.
 f (x) = - 2 * sine (x)

 Vertical translations
 Suppose that k> 0
 To graph y = f (x) + k, move the graph of k units up.
 f (x) = - 2 * sine (x) + 3

 
 C. reflection across the x-axis, vertical stretching by a factor of 2, vertical translation 3 units up

Letter a i would say
