Topics
- Graphing
- Polynomials
- Curves
Description
Learn about graphing polynomials. The shape of the curve changes as the constants are adjusted. View the curves for the individual terms (e.g. y=bx ) to see how they add to generate the polynomial curve.
Sample Learning Goals
- Sketch how the graph of a line changes as the coefficient and constant vary.
- Predict how a line graph will look given an equation in other forms.
- Sketch how a parabola changes as coefficients and constant vary.
- Predict how a parabolic graph will look given equations in other forms.
