First lets look at our graph of y = cos x
***First picture***
Next lets look at a <span>vertical stretch.
***Second picture***
To vertically stretch y = cos x, we need to multiply cos by a number greater than 1. I am going to use 2.
Standard Form: y = cos x (Red Line)
Vertical Stretch: y = 2 cos x (Blue Line)
Lets look at a vertical shrink
***Third picture***
To create a vertical shrink, you multiply the cos by a number less than 1. I am going to use .5
</span>Standard Form: y = cos x (Red Line)
Vertical Shrink: y = .5 cos x (Green Line)
Now lets look at horizontal stretch.
***Forth picture.***
To create a horizontal stretch, you multiply the x by a value less than 1. I am going to use .5
Standard Form: y = cos x (Red Line)
Vertical Stretch: y = .5 cos x (Orange Line)
Finally, to create a horizontal shrink, you multiply the x by a value greater than 1. I am going to use 2.
***Fifth picture.***
Standard Form: y = cos x (Red Line)
Vertical Shrink: y = 2 cos x (Purple Line)

Answer:
A. is correct answer
Step-by-step explanation:
full explanation
Answer:
A table that has (0,0), (-1,1), (-4, 2) and undefined for any positive x value
Step-by-step explanation:
Reflecting across the y axis just changes the x values, it makes them negative. so has points (0,0), (1,1), (4, 2) and so on. reflecting over the y axis makes them(0,0), (-1,1), (-4, 2) and again so on.
Also good to mention in negative x values are undefined, so flipped over the y axis positive x values are undefined.
As for the answer it doesn't look like any of those shown. The first one is close, but the x values would need to swap their signs.
