Algebra 1 · Exponential Functions & Data

Definition

Exponential growth is repeated multiplication by a factor greater than 1, producing a rising curve.

Examples

  • y = 50(1.2)^x grows 20% each step.
  • A population doubling each year shows exponential growth.

Key rule

A base greater than 1 makes the curve rise.

Memory hook

Growth = multiplying by a factor above 1.
