Reflections across the Axes: f(x) = s_o(s_i x - h)
- A B Cron
This applet will demonstrate the basics of linear functions. Slider will change the sign of the slope of the line. What happens when is changed? Slider will change the sign of the coefficient of x. What happens when is changed? Are you sure of yourself? Move the h-slider and do your tests again; do your answers change? Slider h will vary the horizontal translation of the line. The check boxes will turn on up to 3 points for you to calculate the slope of the line. The slope check box will allow you to check your slope. The y=x check box will graph the parent curve with the current line. The full linear equation is displayed at all times.
This applet can be used by teachers in a demonstration mode in the classroom or teachers can have students load it on their own computers with a worksheet to be complete for a grade.
