Here, we will try to find the [b]exact[/b] height of a rice plant (remember, height is a continuous variable).[br][br]Answer the questions below, in your notebook.

[b]Question 1:[/b] The units on the y-axis are in cm. From this, estimate the height of the rice plant.[br][br]From now, to have a clear visualization, push "Show Height Line", to mark on the y-axis the height of the plant.[br][br][b]Question 2: [/b] Push "Zoom on Height" to get a more accurate measurement. Push it twice. Now, estimate the height of the rice plant. Is this the exact height?[br][br][b]Question 3: [/b] Zoom in a few more times to get more accurate. Estimate the height of the rice plant. Is this the exact height?[br][br][b]Question 4: [/b] Continue this process, to get an exact height. Did you arrive at a height? [b]Note: [/b]GeoGebra has difficulty with zooms, so if the red line disappears, push "Center on Line" to go back to the line.
