🎯 Definition
A function is a rule that connects each input number (x) with exactly one output number (y).
💡 Think of it as a vending machine —
😄
you put in a code (x), and it gives you one snack (y).
If the machine gives two snacks for one code — it’s broken (not a function)!
🧮 Notation
We write:
f(x) = y
This means “f is a function of x” and its value is y.
Example:
f(x) = 2x + 3
If you put x = 2,
then f(2) = 2(2) + 3 = 7.
✅ One input → one output.
🧠 Domain & Range
● Domain: All possible input values (x-values).
● Range: All possible output values (y-values).
Example:
If f(x) = 2x + 3
then both domain and range are all real numbers (–∞ to +∞).
