Answer:
The cost is $100.80
Step-by-step explanation:
100% = $140
72% = sale price
140 x 0.72 = $100.80
We have that O(n²) is the theta notation for 7n² + 4n + 2.
Let's give big-Oh a formal definition:
O(g(n)) = {the set of all f such that 0 f(n) cg(n) for any n >= n₀ fulfilling positive constants c and n₀}
To show this
We need to find c and n₀ such that:
7n² + 4n + 2 <= cn² for all n >= n₀ .
Divide both sides by n², getting:
7 + 4/n + 2/(n²) <= c for all n >= n₀ .
If we choose n₀ equal to 1, then we need a value of c such that:
7 + 4 + 2 <= c
We can set c equal to 13. Now we have:
7n² + 4n + 2 <= 13n² for all n >= 1 .
Hence, 7n² + 4n + 2=O(n²)

B. Because a domain is the "x" value and on a graph you would notice the the "x" are all positive numbers (to the left). Hope that made sense. A range is the "y" value and are negative numbers (to the right) on a graph just in case you would like to know that as well:)
Answer:
It should be also zero because it is zero
