Quadratic Graphs
Recognise that quadratic functions produce curved (parabolic) graphs, distinguish them from linear graphs, and use plotted quadratic graphs to estimate values and find approximate solutions
Teaching approaches
Gakuva’s recommended starting approach is selected. You can still compare every option.
1 approach
Can your child recognise that an equation like y = x² produces a curved graph rather than a straight line, and use a plotted curve to estimate values?

Check understanding
- Explain why x² produces a U-shaped curve rather than a straight line
- Plot a simple quadratic such as y = x² − 4 from a table of values
- Read approximate solutions from a quadratic graph (e.g., where y = 0)
