Using a Calculator for Functions

Mr. Bourne, a math teacher from Minnesota, guides viewers through finding the x and y intercepts of a graph using a calculator. The tutorial covers entering a quadratic function into the calculator, adjusting the graph window, and using specific calculator functions to find the intercepts. The video concludes with instructions on finding additional x-intercepts and encourages viewers to subscribe for more content.

What is the main goal of this tutorial?

• To learn how to solve quadratic equations

• To learn how to use a calculator

• To find the x and y intercepts of a graph

• To understand the properties of functions

Which key should you press first to enter a function into the calculator?

• Window

• Graph

• Zoom

• Y=

What is the correct equation to enter for this example?

• 16x^2 + 25x - 6

• -16x^2 - 25x + 6

• 16x^2 - 25x + 6

• -16x^2 + 25x + 6

Why is it necessary to adjust the window settings?

• To change the type of graph

• To better see where the x and y intercepts are

• To zoom in on the graph

• To change the color of the graph

Which key do you press to start adjusting the window settings?

• Zoom

• Trace

• Graph

• Window

What value should you enter for x to find the y-intercept?

• 1

• 0

• Any negative number

• Any positive number

What is the y-intercept of the given function?

• 6

• -16

• 0

• 25

Which option should you choose to find the x-intercept?

• Zero

• Maximum

• Minimum

• Value

What is the x-intercept found on the right side of the graph?

• 0.7738

• 1.7738

• 2.7738

• 3.7738

What should you do if there are multiple x-intercepts?

• Ignore the additional x-intercepts

• Repeat the process to find all x-intercepts

• Find only the negative one

• Find only the positive one
