Answer:
X^5+3x^4+81x+ 243
Step by step:
X^4*x=x^5
X^4*3=3x^4
81*x=81x
81*3=243

General Formulas and Concepts:
<u>Algebra I</u>
- Composite Functions
- Combining Like Terms
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 4x² + 1
g(x) = x² - 5
(f + g)(x) is f(x) + g(x)
<u>Step 2: Find (f + g)(x)</u>
- Substitute: (f + g)(x) = 4x² + 1 + x² - 5
- Combine like terms: (f + g)(x) = 5x² - 4
Answer:
Diameter: 14
Radius: 7
Step-by-step explanation:
