Answer:
{0, 10, 42}
Step-by-step explanation:
<em>Domain is set of input values and range is set output values.</em>
For the function f(x) = 2x² - 8 and domain set of {-2, 3, 5}
<u>Range is:</u>
- f(-2) = 2(-2)² - 8 = 0
- f(3) = 2*3² - 8 = 10
- f(5) = 2*5² - 8 = 42
<u>Range:</u> {0, 10, 42}
Answer:
The value could replace q is 108 - n ⇒ the last answer
Step-by-step explanation:
* Lets study the values of quarters and nickles
- One quarter = 25 cents
- One nickle = 5 cents
- The number of coins is 108
- The coins are nickles or quarters only
- The coins worth $ 21
* Lets solve the problem
∵ The number of coins is 108 coins
- Let the quarter is q and the nickel is n
∴ q + n = 108 ⇒ (1)
∵ The coins worth $21
∵ $ 1 = 100 cents
∴ $21 = 21 × 100 = 2100 cents
∵ The quarter = 25 cents
∵ The nickels = 5 cents
∴ 25q + 5n = 2100 ⇒ (2)
- To find the value which replace q use equation (1)
∵ q + n = 108 ⇒ subtract n from both sides
∴ q = 108 - n
* The value could replace q is 108 - n
