try googling it thats what I would do. I think it would be 1/6 tho
Answer:

Step-by-step explanation:
In order to vertically stretch a function, we just need to multiply the function by our stretch factor.
So, we have the function:

We want to find the equation of this function vertically shrunk by a factor of 1/4. So, multiplied the function by 1/4:

And this will be our answer :)
Answer:
The answer is: (x,y) = (-2,5)
Whoah that's complicated i don't think i can help srry <span />
