Finding Zeros with the TI-84

The video tutorial demonstrates how to find the zeros of a function using a TI-84 series graphing calculator. It begins with entering the function into the calculator, graphing it, and then using the calculator's features to find each zero individually. The process involves setting left and right bounds and making a guess to accurately determine where the graph crosses the x-axis, identifying the zeros at x = -3, x = 0, and x = 2.

What is the primary goal of using a TI-84 calculator in this lesson?

• To calculate derivatives

• To solve a system of equations

• To graph a linear equation

• To find the zeros of a function

Which button do you press first to enter a function into the TI-84 calculator?

• 2nd

• Y=

• Zoom

• Graph

After entering the exponent, what must you do to continue entering the rest of the function?

• Press the Graph button

• Press the Zoom button

• Arrow to the right

• Press Enter

What is the purpose of using the Zoom feature on the TI-84 calculator?

• To change the color of the graph

• To adjust the view of the graph

• To solve the equation

• To enter a new function

What does it mean when a graph crosses the x-axis?

• The function is undefined

• The function has a minimum point

• The function has a maximum point

• The function has a zero

Which menu option do you select to find a zero on the TI-84 calculator?

• 4: Maximum

• 3: Minimum

• 2: Zero

• 1: Value

What is the first step in finding a zero using the calculator?

• Make a guess

• Set the Left Bound

• Enter the function

• Set the Right Bound

What is the x-value of the first zero found in the lesson?

• x = 1

• x = 0

• x = -3

• x = 2

What is the second step after setting the Left Bound when finding a zero?

• Press the Graph button

• Set the Right Bound

• Zoom in on the graph

• Enter a new function

What is the x-value of the second zero found in the lesson?

• x = -3

• x = 1

• x = 0

• x = 2
