Understanding Graphing and Coordinate Planes

The video tutorial reviews graphing basics, focusing on linear and quadratic functions. It explores how changing the Y-axis to a quadratic scale affects the appearance of graphs, making quadratic functions appear linear and linear functions appear non-linear. This demonstrates the impact of different scales on graph interpretation.

What is the purpose of labeling axes when graphing?

• To add artistic elements

• To make the graph look colorful

• To identify the scale and values

• To confuse the viewer

What does the graph of a linear function typically look like?

• A curve

• A zigzag line

• A straight line

• A circle

How does the slope of a linear function change when the equation is y = 2x?

• The slope becomes steeper

• The slope remains the same

• The slope becomes zero

• The slope becomes less steep

What is the shape of the graph of a quadratic function like y = x^2?

• A circle

• A triangle

• A parabola

• A straight line

Why was the y-axis labeled with squares of numbers in the non-linear scale section?

• To make the graph more complex

• To demonstrate a quadratic scale

• To simplify calculations

• To confuse the viewer

What happens to the graph of y = x^2 when plotted on a quadratic y-axis?

• It disappears

• It remains a parabola

• It looks like a line

• It becomes a circle

How does a linear function appear on a quadratic y-axis?

• As a curve

• As a parabola

• As a straight line

• As a zigzag

What is the effect of using a logarithmic scale on the y-axis?

• Linear functions look like curves

• Logarithmic functions look like lines

• Quadratic functions look like circles

• All functions look the same

What is a common use of non-linear scales in graphing?

• To confuse the viewer

• To make graphs look artistic

• To make graphs more colorful

• To simplify complex data representation

What happens to quadratic functions on a coordinate plane with a quadratic y-axis?

• They remain unchanged

• They look like zigzags

• They look like lines

• They look like circles
