Answer:
See explanation below.
Explanation:
Let's assume that we have an original function
and let's suppose that we have a constant
and if we define this new function:

We see that if c>1 the dunction would be vertically stretched by c units.
And if
we see that we will have a vertically shrinking by a factor of c units
So for example we can use the following function:

For this case our constant is c=0.75 and we can define the new function like this:

We will see if we plot the two figures that we have a vertical shrinking of 0.75 units.
