Graphing Functions and Quadrants

Ryan Malloy from the Worldwide Center of Mathematics explains how to create a four quadrant graph. He discusses the significance of each quadrant, where both X and Y can be positive or negative. The video demonstrates graphing a linear function, plotting points, and drawing lines. It also explores different functions like parabolas and cubic functions, emphasizing the simplicity of graphing by plugging in input values and connecting the dots.

Why are single quadrant graphs often used in modeling natural phenomena?

• Because they are easier to draw

• Because they are more accurate

• Because natural values are often positive

• Because they require less data

What is the first step in graphing a linear function?

• Setting up tick marks

• Choosing a function

• Labeling the quadrants

• Drawing the axes

Where will the point be if the input value is negative?

• On the top half

• On the bottom half

• On the right side

• On the left side

What should you do to avoid confusion when labeling tick marks?

• Label them alphabetically

• Use larger numbers

• Use different colors

• Label them as positive or negative

If X is zero in the function 3x - 2, what is the value of Y?

• 0

• 2

• 3
