## How do you find the intercepts on a calculator?

Press the “2nd” key then the “Calc” key. This accesses the trace menu. Scroll down to “Zero” and press “Enter.” Using the arrow keys, scroll to the left of the X intercept and press “Enter.” Scroll to the right of the intercept and press “Enter'” twice. The X intercept will be displayed the bottom of your screen.

**How do you find the intersection on a TI 83 Plus?**

TI-83

- Press Calc (2nd Trace)
- Choose Intersect (#5)
- For the First Curve, hit enter.
- For the Second Curve, hit enter.
- For the Guess, arrow to the intersection and press enter.
- The TI-83 will return a value for x and y. Both of these coordinates are part of the solution.

**What can you do with a TI-84 calculator?**

You can use your graphing calculator for algebra, trigonometry, precalculus, and calculus; you can even use it to write programs and games. If you’re a student or teacher, a graphing calculator can be used in every math subject from middle school to college, as well as in science and computer classes.

### How do you find the intersection on a TI-84 calculator?

You can use the TI-84 Plus calculator to find accurate points of intersection for two graphs. Using the arrow keys in a graph activates a free-moving trace. However, using a free-moving trace rarely locates the point of intersection of two graphs but instead gives you an approximation of that point.

**How do you find the intersection on a TI 84 calculator?**

**How do you open the solver on a TI-84 Plus CE?**

Access the Numeric Solver by pressing the [Math] button, and then pressing the up arrow key to select the last option. Press enter to open it. You should now see the equation solver screen. The two boxes that are displayed represent the two sides of the equation.

#### Can TI-84 factor equations?

To factor on a TI-84, you can use the Equation Solver function. To access it, press the MATH button on your calculator, then hit the up arrow to scroll directly to the bottom of the list. Press ENTER and input the equation. You can also add a custom program to your calculator to more easily factor polynomials.

**Is a TI-83 better than a TI-84?**

The TI-83, the base model, has 160 kilobytes (KB) of memory and 24 KB of RAM. The TI-84, sometimes referred to as the “TI-84 Plus,” boasts 480 KB of memory but the same amount of RAM as the TI-83. However, the TI-84 has twice the processing speed.

**How do you find the points of intersection on a TI 84 Plus?**

Graph the functions in a viewing window that contains the point of intersection of the functions. Press [2nd][TRACE] to access the Calculate menu. Press [5] to select the intersect option. Select the first function.

## How do you find the point of intersection of two functions?

When the graphs of y = f(x) and y = g(x) intersect , both graphs have exactly the same x and y values. So we can find the point or points of intersection by solving the equation f(x) = g(x). The solution of this equation will give us the x value(s) of the point(s) of intersection.
