Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 3x² - 7x
f(-2) is x = -2
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(-2) = 3(-2)² - 7(-2)
- Exponents: f(-2) = 3(4) - 7(-2)
- Multiply: f(-2) = 12 + 14
- Add: f(-2) = 26

Answer:
Step-by-step explanation:
You have the formula written correctly, so now we just need to fill it in with what we have. Our principle, or initial investment, is 21,000; our interest rate of 4.6% as a decimal (always as a decimal!) is .046; and our interest earned is 900. We need to find t. Setting up with what we have:
21000(.046)(t) = 900 and
966t = 900 and
t = .931 years
.9 of a year is the same as 10.8 months or so.

Answer:
h > 0, only integers
Step-by-step explanation:
One can only buy integer numbers of packages of hotdogs, so the domain is integer values.
Since we "must" buy more than 0 packages, the appropriate domain specification is ...
h > 0, only integers
