Exploring Domain and Range from Graphs

What is the primary focus of the three-day lesson plan?

• Reviewing previous lessons

• Learning about domain and range

• Solving complex equations

• Understanding calculus concepts

How should you write the interval notation for x values less than or equal to -2?

• (-∞, -2)

• (-2, ∞)

• [-2, ∞)

• (-∞, -2]

What does an open circle on a graph indicate?

• The value is infinity

• The value is zero

• The value is excluded

• The value is included

When determining the domain, which axis should you focus on?

• X-axis

• Z-axis

• W-axis

• Y-axis

In interval notation, how should you list the range from lowest to highest value?

• Highest to lowest

• Top to bottom

• Left to right

• Bottom to top

What is the domain of a function that starts at x = 0 and extends to positive infinity?

• (0, ∞)

• [0, ∞)

• (-∞, 0]

• (-∞, ∞)

If a function's range is from -4 to positive infinity, how should it be written in interval notation?

• (-∞, -4]

• (-∞, ∞)

• [-4, ∞)

• (-4, ∞)

What does it mean if an arrow on a graph points to the right?

• The function continues to positive infinity

• The function is undefined

• The function continues to negative infinity

• The function ends

How should you write the domain of a function that extends from negative infinity to positive infinity?

• (-∞, ∞)

• (-∞, 0]

• [0, ∞)

• (-∞, -∞)

What is implied if a function does not show an open or solid circle at a point?

• The point is included

• The point is zero

• The point is excluded

• The point is undefined
