Quadratic Graphs
Quadratics
- Quadratic equations contain an x^2 term
- Quadratic equations have curved graphs
- You can draw the graph of a quadratic equation by completing a table of values
Drawing quadratic curves
- Use a sharp pencil
- Plot the points carefully
- Draw a smooth curve that passes through every point
- Label your graph
- Shape of graph will be either u or n
- Drawing a smooth curve
- It’s easier to draw a smooth curve if you turn your graph paper so your hand is inside the curve
- Check it
- All the points on your graph should lie on the curve
- If one of the points doesn’t fit then double check your calculations
