Answer:
(-2, 4) U [7, ∞)
Step-by-step explanation:
The domain of a function is the set of inputs at which the functions is defined. Usually determined by the x-values. In this problem we have the graph of a function. At x = -2 the function is not defined, we can see this by taking a look at the opened circle at this value in the graph. Then the function takes values until x = 4. Notice that at x = 0 the function is defined. At x = 0 to left the function takes the value y = 0 and at x = 0 to the right the function takes the value y = -1. Then the function takes value at x = 7 (including this value because of the closed circle in the graph) and beyond. Therefore, the correct answer is:
(-2, 4) U [7, ∞)
The answer is A. 4(n 3) - 6n
Answer:
=−13m−28
Step-by-step explanation:
Let's simplify step-by-step.
2−13m−30
=2+−13m+−30
Combine Like Terms:
=2+−13m+−30
=(−13m)+(2+−30)
=−13m+−28
Answer:
the 4 one
Step-by-step explanation:
Presley should prepare 712 books for the school book sale.
1 stall = 40 books on the shelf and 2 boxes of books
8 stalls = 40(8) + 2(12)(8)
= 320 + 24(8)
= 320 + 192
= 512 books in the stalls
books in the stalls = 512
books in inventory = <u>200</u>
total number of books 712
