to vertically strech or shrink a function, multily the whole function by the factor taht you want to strech or shrink it by

to horizontally strech or shrink a function, multiply every x by the factor you want to strech or shrink it by

shrinks mean multiplying by a value greater than -1 and less than 1
stetch means multiply by a value greater than 1 or less than -1

first one
horizontal shrink
muliply every x by a fraction
so that is A

2nd one
vertical strech
multiply whole function by a value greater than 1 or less than -1
D is the answer

3rd one
horizontal strech
multiply every x by a value greater than 1 or less than -1
C is the answer

4th one
vertical shrink
multiply whole function by a value greater than -1 and less than 1
B is the answer

There are ways to shrink a function. The answers to the questions are below;

  • The transformation  cos(x/5) results in a horizontal shrink.
  • The transformation  -5cos(x) results in a vertical stretch.
  • The transformation cos(7x) results in a horizontal stretch.
  • The transformation  2/3cos(x) results in a vertical shrink.

What are shrinks or stretches?

Stretches and shrinks (such as horizontal and vertical) are known to pull the base graph outward and they can also compress the base graph inward. They tend to alter the total dimensions of the base graph without changing its shape.

The vertical stretching/shrinking is known to alter the y -values of points. The  transformations that influence the y -values are known to be intuitive.

The Horizontal stretching/shrinking is known to also alter the x -values of points hence the  transformations that influence the x -values are regarded as counter-intuitive.
