The Domain of f(x) is real number and the range is y ∈ [-∞, 4].
<h3>What is Modulus function?</h3>
A modulus function is a function which gives the absolute value of a number or variable. It produces the magnitude of the number of variables. It is also termed as an absolute value function.
Here, f(x) = - |x| + 4
Domain of f(x) = Real Number
Range of f(x) ; f(x) ≤ 4
y ∈ [-∞, 4]
Key features:
1. The minus before the |x| reflects the function in the x-axis. So it will still be V-shaped but instead but reflected in the x-axis.
2. The +4 moves the function vertically 4 units upwards.

Answer:
40 days saw either rain or high winds
Step-by-step explanation:
We solve this question using Venn sets.
I am going to say that:
Set A: Rain
Set B: High winds.
18 days saw rain
This means that
29 days saw high winds
This means that
7 days saw both rain and high winds.
This means that
How many days saw either rain or high winds?
This is
Sp
40 days saw either rain or high winds
X + x + x + 20 + 10 = 180
(combine like terms)
3x + 30 = 180
3x=180-30
3x=150
x=150/3
x=50
1 pound is 16 ounces.
16 /2 = 8
Multiple 4.29x2 (Below)
$4.29 (8 ounce package of cheese) x 2 = $8.58
s= original price of shoes
n= new price of shoes
s+0.05s=n
