Increasing function

Definition

A function whose values rise as $x$ increases over an interval; a positive derivative, $\frac{dy}{dx}>0$ , shows this.

Used by AQA

Specification 4.5, 4.7 · Paper 1, Paper 2

An increasing function rises as you move right. Its tangent slopes upwards, so its gradient is positive. A decreasing function falls as you move right.

A function whose y-value rises as x increases over an interval. A positive derivative, $\frac{dy}{dx}>0$ , indicates increasing behaviour.
