What are you supposed to be doing
Answer:
domain: [- ∞ , ∞]
range: (8 , -∞]
Step-by-step explanation:
- ∞ < x < ∞
y < 8
Answer:
D.(x,y) → (x,-y)
Step-by-step explanation:
If it is reflected across the X-axis, then the X variable will stay the same and the Y variable will change.
I hope this helps!! Good luck!!
(Sorry if I'm wrong! It's kinda awkward because it is placed in the second quadrant instead of the first.)
Answer:
The result after adding a set of numbers or is called a sum.
Step-by-step explanation:
Consider the provided information.
The four mathematical operations are:

The sign + is used to add numbers.
The sign - is used to subtract the numbers.
The sign × is used for the product of the numbers.
The sign ÷ is used for division of the numbers.
When we add two or more number by using the operator + the obtained number or value is called the sum of the numbers.
For example:
Consider the number: 2 + 5 if we add the number the resulting value will be 7.
The number 7 is the sum of 2 and 5.
Thus, the result after adding a set of numbers is called a sum.
