Push Y= and type the function in the first row.
Graph:
It is a vertical shrink by a factor of 11000 of the graph of y=- 4x^2.
Let's enter the function in the calculator by pushing Y= and typing it in the first row.
We may want to zoom out by changing the window settings. To do this, push WINDOW and change the settings to a much bigger window. Then push GRAPH once more to draw the equation with these new settings.
We see that the graph of y=- 0.004x^2 is a vertical shrink by a factor of 11000 of the graph of y=- 4x^2.
Let's enter y=- 4x^2 in the calculator by pushing Y= and typing it in the first row.
Next, by pushing GRAPH, the calculator will draw the graph of the equation.
To see the difference between the graphs, let's zoom out by changing the window settings. To do this, push WINDOW and change the settings to a much bigger window. Then push GRAPH once more to draw the equation with these new settings.
