ONLINE GRAPHING WORKFLOW GUIDE
TI-84 style graphing workflows — independently online
Use an online graphing workflow for the tasks many students associate with a handheld graphing calculator: entering functions, adjusting a window, inspecting a table, tracing values, and checking intersections. SolveGrid is independent and not affiliated with Texas Instruments.FORMULA
y = f(x)WORKED EXAMPLE
Enter y = x² − 4 and y = 2x + 1, then inspect the graph and table to estimate their intersections.STEP BY STEP
Enter one relationship per graph line
Use a separate y = expression for each function you want to compare. An expression such as y = 2x + 1 is a line; y = x² − 4 is a parabola. The SolveGrid Graphing Calculator also accepts a vertical line such as x = 3.
Set a useful graph window
Choose x and y limits that include the important part of the functions. A window that is too wide can hide detail, while one that is too narrow can cut off roots or intersections.
Use graph, table, and trace together
The graph gives the overall shape. The table helps inspect exact input-output pairs, and trace values help check a particular x-coordinate before making a conclusion.
Use a focused tool for the next method
For coefficients or algebraic solutions, move to the Equation Solver. For matrices, statistics, or polynomial roots, use their dedicated workspaces instead of forcing every task into one graph screen.
