Graphing examples

Work through a graph.

Start with an equation, check its values, and change one thing at a time. Each example opens in the full graphing calculator when you want to explore further.

y = ax + 1

Make a table of values from an equation

Build a table for y = 2x + 1, inspect its points on a graph, and see how changing the slope changes the values.

y = ax² − 4

Explore a quadratic function with a slider

Graph y = ax² − 4, compare a table of values, and explore how the coefficient changes the direction and shape of a parabola.

y = a sin(x)

See how amplitude changes a sine graph

Adjust a in y = a sin(x), compare points and table values in radians, and understand amplitude, reflection, and period.
