A and B must be disjoint. You have, by the inclusion/exclusion principle, that
where the last term is required to prevent double counting. When
and
are disjoint, you have

Answer:
Step-by-step explanation:
A simple fraction (also known as a common fraction or vulgar fraction, where vulgar is Latin for "common") is a rational number written as a/b or {\displaystyle {\tfrac {a}{b}}}
b

Answer:
f(x) = x² + 5
General Formulas and Concepts:
<u>Algebra I</u>
- Equality Properties
- Function Notation
Step-by-step explanation:
<u>Step 1: Define</u>
y - x² = 5
<u>Step 2: Rewrite</u>
- Add x² to both sides: y = x² + 5
- Rewrite <em>y</em>: f(x) = x² + 5
