Key Features of Functions: Day 1 Insights

What are the learning goals mentioned in the video?

• Graphing linear functions

• Finding key features and using correct notation

• Understanding calculus concepts

• Solving equations and inequalities

Where does the graph cross the x-axis?

• (1, 0) and (3, 2)

• (0, -1) and (3, 1)

• (-1, 0) and (3, 0)

• (0, 3) and (1, 4)

How are zeros written differently from x-intercepts?

• Both are written as points

• Both are written as equations

• Zeros are written as points, x-intercepts as equations

• Zeros are written as equations, x-intercepts as points

Where does the graph cross the y-axis?

• (1, 4)

• (-1, 0)

• (3, 0)

• (0, 3)

What are turning points in a graph?

• Points where the graph is constant

• Points where the graph changes direction

• Points where the graph crosses the y-axis

• Points where the graph crosses the x-axis

What is the domain of the given graph?

• From -2 to 3

• From -3 to 2

• From -1 to 4

• From 0 to 3

How is the domain written in interval notation?

• (-2, 3)

• [-2, 3)

• [-2, 3]

• (-2, 3]

What is the range of the given graph?

• From -2 to 3

• From -5 to 4

• From -4 to 5

• From -3 to 4

What is the maximum value of the graph?

• 6

• 5

• 4

• 3

Why can't the minimum value be determined?

• The graph has an open point at the minimum

• The graph is not defined at the minimum

• The graph has a closed point at the minimum

• The graph does not have a minimum value
