Solutions by Graphing Systems

The video tutorial demonstrates how to use a graphing calculator to solve systems of equations graphically. It covers entering linear and nonlinear equations, adjusting the viewing window for better visibility, and using the intersect function to find points of intersection. The tutorial provides step-by-step instructions for both linear and nonlinear systems, highlighting the trial-and-error process of adjusting the viewing window and the use of the calculator's intersect function to find exact or approximate solutions.

What is the first step in solving a system of linear equations graphically using a calculator?

• Adjust the viewing window

• Use the intersect function

• Enter the equations into the calculator

• Press the graph button

When using the intersect function, what should you do after selecting the first curve?

• Select the second curve

• Adjust the X and Y scales

• Press the graph button

• Enter a new equation

What type of functions are involved in the second system of equations discussed in the tutorial?

• Nonlinear functions

• Quadratic functions

• Linear functions

• Exponential functions

How do you find the absolute value function on a graphing calculator?

• Press the graph button

• Use the variable button

• Hit math and navigate to number

• Press the Y equals button

What is the purpose of adjusting the viewing window when graphing nonlinear equations?

• To change the color of the graph

• To make both points of intersection visible

• To zoom in on the X-axis

• To reset the calculator

What should you do if the first point of intersection is not clearly visible?

• Change the equation

• Adjust the viewing window

• Use a different calculator

• Ignore the point

What is the difference between exact and approximate solutions in the context of this tutorial?

• Approximate solutions are more accurate

• Approximate solutions are only used for linear equations

• Exact solutions are precise values, while approximate solutions are rounded

• Exact solutions are always integers
