Functions and graphs.

A graph shows how one quantity changes when another changes.

Learning outcome: Read slope, intercept, domain and units from an engineering graph.

Read slope, intercept, domain and units from an engineering graph. Diagram is schematic and not to scale.

Core ideas

Build the model

function notation and domain.

linear, quadratic and exponential models.

slope as a rate with units.

Engineering bridge

Where it is used

motion, forces, and energy
probability and experimental reasoning

Original Lilerno structure and wording. Visuals are conceptual, inputs are not a design specification, and practical work requires appropriate supervision.
