How to Graph on a TI-84 Plus Calculator: Step-by-Step Guide

The graphing calculator TI-84 calculator online is a widely used tool among secondary and post-secondary students. It is especially beneficial to imagine tasks, solve equations, and analyze data in subjects such as algebra, geometry, calculus, and statistics. Mastery of the TI-84 Plus’s grading capabilities can increase your efficiency and enrich your understanding of mathematical concepts.

This will clarify the processes for grading training equations, changing windows, changing points, and analyzing intersections with clarity & accuracy and give user the idea that how to graph on a TI-84 plus.

Step 1: Open the Graph Menu & Start Learning how to graph on a ti-84 plus

TI 84 and TI 84 Plus CE both have the graphing capabilities as well as scientific calculator capabilities like of TI 30 Scientific calculator. To kick off your graphing journey on the TI-84 Plus:

  • Hit the [Y=] button located in the upper-left corner.
  • You’ll see several lines labeled Y1=, Y2=, Y3=, and so on.
  • Type your equation into one of those lines.

For example, to graph y = x² – 2x + 1, you would enter:
X, T, θ, n → X² – 2X + 1

Step 2: Analyzing the Graph

  • Once you’ve entered the equation:
  • Press [GRAPH] to display it.

Parabola y = x² – 2x + 1 appears on the screen.

If the graph seems too small or too large, adjust the window settings. Visualization in a Graphing Calculator is key element to get best out of it

Step 3: Modifying the Window

The [Window] button allows you to change the visibility of the graph.

To increase visibility, consider adjusting these parameters:

  • Xmin = -10
  • Xmax = 10
  • Ymin = -10
  • Ymax = 10
  • Xscl = 1 (this is the scaling factor for the x-axis)
  • Yscl = 1 (this is the scaling factor for the y-axis)

After you set these parameters, press [GRAPH] again. A well-focused graph of your feature should now be visible. The window of each TI Calculators Online is different due to the difference of their capabilities.

Step 4: Tracing and Evaluating Points

The [Trace] button enables navigation with graphs to identify special locations.

For y = x² – 2x + 1, using the TRACE function will show you points like (0,1), (1,0), and (2,1).

This makes it easier to identify intercepts and understand the curve’s shape.

Step 5: Graphing Multiple Functions

The TI-84 Plus allows you to graph multiple functions simultaneously.

Here’s the text to analyze: Let’s compare the equations y = x² and y = 2x + 3.

  • First, head over to [Y=].
  • Type in Y1 = x².
  • Then, for Y2 = 2x + 3.
  • Now, hit [GRAPH].

You’ll see both graphs, which makes it easy to spot where they intersect.

Step 6: Finding Intersections

To find those intersection points:

  • Hit [2nd] → [TRACE] (Calc menu).
  • Choose 5: Intersect.
  • Use the arrow keys on TI 84 or TI 84 Plus CE Keyboard to select the first curve, then hit ENTER.
  • Next, pick the second curve and press ENTER again.
  • Move the cursor close to where they meet and hit ENTER once more.

The TI-84 will display the coordinates of that intersection.

Step 7: Graphing Inequalities

You can also graph inequalities like y ≤ x².

  • Go back to [Y=].
  • Enter the function.
  • Press the left arrow until the cursor highlights the sign next to Y1=.
  • Choose either < or ≥ from the options available.
  • Then, hit the [GRAPH] button.

The shaded area indicates the solution region.

Example Problem

Let’s plot the equations y = x² – 4 and y = 2x + 1, and find their points of intersection.

  • 1: Input Y1 = x² – 4.
  • 2: Input Y2 = 2x + 1.
  • 3: Press the [GRAPH] button.
  • 4: Now, navigate to [2nd] → [TRACE] → 5:Intersect.
  • 5: Position the cursor near the first intersection and hit ENTER three times.
  • You’ll get the result: (–1.56, –2.12).
  • 6: Now, do the same for the next intersection.
  • You’ll find: (2.56, 6.12).

This shows the intersection points of the parabola and the line.
