What is Xscl in graphing calculator?
By setting Window variables, you can define the viewing window’s boundaries. It’s important to set appropriate boundaries to obtain an accurate view of the graph. xmin, xmax sets the boundaries on the x axis ymin, ymax sets the boundaries on the y axis xscl, yscl sets the distance between tick marks on each axis.

What does zoom 6 do on a graphing calculator?
Press ZOOM 6 to draw a graph of your equation between the values of -10 and 10 for both x and y.
How do you zoom out on a calculator?
keys to move the cursor (the cursor looks like a + sign) to the spot on the screen from which you want to zoom in or zoom out. Then press [ENTER]. The graph is redrawn centered at the cursor location. You can press [ENTER] again to zoom in closer or to zoom out one more time.
Where is the zoom button on a calculator?
Using “Zoom” When you graph this equation without changing the window size you will get the screen below. This is not very helpful, but luckily we can change the lengths of the X and Y axes to give us a better picture. From the graph press the [zoom] key located in the middle of the top row of keys.
How do I use ZBox?
The ZBox command allows you to define a new viewing window for a portion of your graph by enclosing it in a box.
- Zoom In and Zoom Out: After the graph is drawn, these commands allow you to zoom in on a portion of the graph or to zoom out from the graph.
- Press [ZOOM][2] to zoom in or press [ZOOM][3] to zoom out.
How do you know if a vertex is minimum or maximum?
One important feature of the graph is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value.
Are all endpoints critical points?
Since an absolute maximum must occur at a critical point or an endpoint, and x = 0 is the only such point, there cannot be an absolute maximum. A function’s extreme points must occur at critical points or endpoints, however not every critical point or endpoint is an extreme point.
Is every critical point an extrema?
Occurrence of local extrema: All local extrema occur at critical points, but not all critical points occur at local extrema.
Can a cusp be a critical point?
As illustrated by the graphs, corners or cusps can be local extreme points and are hence critical points.
