# Graph of $$$y = f{\left(x \right)} = - \left(x + 8\right)^{2} - 1$$$

To draw a parabola, circle, ellipse or hyperbola, choose the "Implicit" option.

You can pass a function as a parameter: https://www.emathhelp.net/en/calculators/calculus-1/online-graphing-calculator/?y=sin(x)&y=cos(x) will draw y=sin(x) and y=cos(x).

*Pan the graph (move it) by holding the Shift key and dragging the graph with the mouse.*

*Zoom the graph in and out by holding the Shift key and using the mouse wheel.*

*The above operations can be very slow for more than 2 graphs. To avoid it, delete all graphs, pan and zoom,
and then plot the graphs again.*
