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|
Answer: 7%
Step-by-step explanation:
Answer:
The value of the expression at x=5 is 10
Step-by-step explanation:
The given expression is 
Let us simplify this expression.
Distribute -2 over the parentheses, we get
Now, substitute x = 5, we get
On simplifying, we get
The value of the expression at x=5 is 10
it's 0.4 while it may look like 4% it's actually 40% of 1
