Answer:
BELOW
Step-by-step explanation:
SO lets think about the information they give us.
Khan acadamy says that we have -3 x and 5 x.
So that just means that the quadratic at 0 has one curved line at -3x and another at 5x. Note that you should put the green dot on the top right on either -3x or 5x to do this.
Then they say the minimum is -4 y.
This just means that when x is 0, y should be -4. Note that you should put the midddle bottom green dot at -4 y exactly on the black line, which is at 0 x.
Green dot top right: (-3 or 5, 0)
Green dot middle bottom: (0, -4)
Hope this helps! ;)
Answer:
don't know how to answer that lol
Step-by-step explanation:
Answer: Choice A -- f(x) = (1/3)*|x|
============================================
The input of a function is x and the output is y = f(x)
To vertically compress a function, we will multiply the y value by some fraction smaller than 1. This is so that the y coordinates are a fraction of what they once were.
In this case, we multiply y by 1/3 so that something that has a y coordinate of y = 81 becomes y = 27 (divide by 3)
So we have y = f(x) become (1/3)*y = (1/3)*f(x) = (1/3)*|x|
I am not 100% sure but I think the answer is C I hope I helped you and Good luck
