What Is a Function Graph? First Look
A function graph is a visual story of how one quantity changes based on another. Here is a clear example through plant growth.
Two connected quantities
A plant's height changes every week. Week is one quantity, height is another. A graph shows this connection as a picture.
💡 Anchor: measure a real plant every week, record the numbers, then plot the points together on a graph.
Reading a simple graph
The line goes up — the plant is growing. The line is flat — growth has stopped. The steepness of the line shows how fast the change is happening.
