2nd MEM; #7 Reset; #1 All RAM; #2 Reset

How do you pull up the last thing calculated on this calculator?

Push 2nd QUIT (MODE)

Which feature inserts a missing number or sign during entry?

2nd INS (DEL)

What does CATALOG do?

Lists all available calculator features in alphabetical order.

What display options does MODE affect, and what are two useful items?

MODE changes number format between NORMAL and SCIentific notation; Float controls the number of decimals shown.

What is STAT PLOT used for and how do you access it?

Creates scatter plots, line graphs, and other plots; access with 2nd Y =.

What is Y= used for on this calculator?

Enter equations to be graphed and/or calculated.

What is TBLSET used for?

Sets up the TABLE; includes TblStart, ΔTbl, Indpnt (Auto/Ask), Depend (Auto/Ask).

What does WINDOW allow you to adjust?

View of the coordinate plane; set Xmin, Xmax, Xscl, Ymin, Ymax, Yscl.

What does FORMAT do, and is it commonly adjusted?

Changes coordinate plane presentation; generally not adjusted.

What is ZOOM used for?

View the coordinate plane in different ways; includes ZBox, Zoom In/Out, ZStandard, ZoomSTAT, ZoomFit.

What does CALC do?

Generates answers based on graph; find zeros, minima, maxima, intersections, etc.

What does TRACE do?

Traces along the graph showing x and y values.

What does TABLE do?

Displays ordered pairs in a table after entering equations in y =.

What is GRAPH used for?

Displays graphs after entering equations into y =.

What are the steps to find the intersection points of two graphs using CALC?

Enter equations in y=; Graph; Zoom if needed; 2nd CALC (TRACE); 5: Intersect; select first line then second line; ENTER.

What are the steps to find zeros (x-intercepts) using CALC?

Enter equation in y=; Graph; Zoom if needed; 2nd CALC (TRACE); 2: Zero; move to intercept; select left side then right side; ENTER.

What are the steps to locate the vertex (minimum or maximum) using CALC?

Enter equation in y=; Graph; Zoom if needed; 2nd CALC (TRACE); 3: Minimum or 4: Maximum; select left side then right side; ENTER.

How do you graph ordered pairs as a scatter plot using STAT?

STAT → 1: Edit; enter x values into L1 and y values into L2; ensure STAT PLOT is On (2nd STAT PLOT, On); Graph; if needed, Zoom → 9: ZoomStat.

How do you perform a linear regression with STAT?

Graph the data with STAT; STAT → CALC → LinReg (ax + b) → ENTER.

How do you perform a quadratic regression with STAT?

Graph the data with STAT; STAT → CALC → QuadReg → ENTER.

How do you perform an exponential regression with STAT?

Graph the data with STAT; STAT → CALC → ExpReg → ENTER.

How do you enable the diagnostic display for the correlation coefficient r during regression?

2nd CATALOG (0) → select DiagnosticOn → ENTER twice.

What is the purpose of ZBox in the ZOOM menu and how do you use it?

Create a box around a location and zoom into it; Graph → ZOOM → ZBox → Enter to start → use cursor to resize → Enter.

How do you perform a Zoom In operation?

Graph a function; ZOOM → Zoom In → move cursor to the area to zoom into → ENTER.

How do you perform a Zoom Out operation?

Graph a function; ZOOM → Zoom Out → move cursor to the area to zoom out from → ENTER.

What does ZStandard do?

Returns to the original view of the coordinate plane.

What does ZoomStat do?

Zoom to the points of your scatter plot.

What does ZoomFit do?

View the entirety of the plotted item.
