Graphing Functions and Finding Intercepts

This video tutorial demonstrates how to use a free online graphing calculator to graph functions, adjust the viewing window, and determine intercepts. It covers entering functions using function notation, adjusting the graph window for better visibility, and finding both horizontal and vertical intercepts for two functions, f(x) and g(x). The tutorial provides step-by-step instructions for using the calculator's features, including changing graph colors and using the calculation tab to find roots or zeros.

What is the first step in using the online graphing calculator?

• Change the graph color

• Determine the intercepts

• Adjust the window size

• Enter the functions

Which key is used to enter an exponent in the graphing calculator?

• Shift + 6

• Alt + 5

• Ctrl + 6

• Shift + 5

What should you do if both graphs are not visible on the coordinate plane?

• Adjust the window

• Change the graph color

• Restart the calculator

• Re-enter the functions

How can you find the horizontal intercepts for f(x)?

• By determining the roots or zeros

• By changing the graph color

• By entering f(0)

• By adjusting the window

What is the vertical intercept for f(x)?

• (0, 0)

• (0, 5)

• (0, 2.75)

• (0, -2.75)

What is the purpose of drawing a box around the x-intercept?

• To adjust the window

• To find the root or zero

• To change the graph color

• To enter a new function

What is the approximate x-intercept on the right for f(x)?

How do you find the vertical intercept for g(x)?

• By changing the graph color

• By entering g(0)

• By determining the roots

• By adjusting the window

What is the vertical intercept for g(x)?

• (0, -2.75)

• (0, 5)

• (0, 7.071)
