Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 4 - x²
g(x) = 2x + 5
<u>Step 2: Find g(-2)</u>
- Substitute in <em>x</em> [Function g(x)]: g(-2) = 2(-2) + 5
- Multiply: g(-2) = -4 + 5
- Add: g(-2) = 1
<u>Step 3: Find f(g(-2))</u>
- Substitute in <em>x</em> [Function f(x)]: f(g(-2)) = 4 - (1)²
- Evaluate exponents: f(g(-2)) = 4 - 1
- Subtract: f(g(-2)) = 3
Step-by-step explanation:
The domain of f(x) is all values of x for which f(x) is defined.
For f(x) to be defined, the expression under the radical must be non-negative.
Therefore, the domain is x ≥ 0, or in interval notation, [0, ∞).
Answer:
M
Step-by-step explanation:
Normally 7 envelopes but on rare occasions, there may be more due to If the packages are filled with Envelopes. Also depending on if the 7 packages are boxes of envelopes, and in that case, 140 envelopes times 7, which would be 980 envelopes in the 7 packages. 140 * 7 = 980.
