Select the correct answer.
The parent cosine function is shifted 5 units left, then vertically stretched by a factor of 4 and shifted up 2 units. Which statement is true about the graph of the transformed function?
A. midline is y=8
B. midline is y=5
C. midline is y=4
D. midline is y=2

Respuesta :

Answer: d y=2

Step-by-step explanation:

Using shifting concepts, it is found that the midline is y = 2, given by option D.

--------------------------------

  • For the parent function [tex]y = \cos{x}[/tex], the midline is at [tex]y = 0[/tex].
  • If the function is shifted up or down, the midline will also be shifted up or down.
  • In this question, the parent function is shifted up 2 units, thus, the midline is also shifted up 2 units, and will be given by y = 0 + 2 = 2.
  • The correct option is D.
