Creating Artwork with Quadratic Functions

This lesson demonstrates how to create artwork by graphing quadratic functions with domain restrictions on the coordinate plane. The video explains the role of parameters a, c, and d in the equation y = a(x-c)^2 + d, affecting the parabola's orientation, horizontal shift, and vertical shift. Using Desmos, the tutorial shows how to adjust graph appearance and expand artwork by adding equations. The lesson concludes with a reflection on the educational value of creating artwork through graphing.

What does the parameter 'a' in the quadratic equation y = a(x - c)^2 + d determine?

• The horizontal shift of the parabola

• The vertical stretch or compression of the parabola

• The color of the graph

• The domain of the function

If the value of 'a' is less than zero, how does the parabola open?

• Downwards

• To the right

• Upwards

• To the left

What effect does the parameter 'c' have on the graph of a quadratic function?

• It shifts the graph horizontally

• It changes the color of the graph

• It determines the domain

• It shifts the graph vertically

In Desmos, what happens when you click the wrench and select reverse contrast?

• The graph becomes invisible

• The coordinate plane turns black and the graph turns white

• The graph changes color randomly

• The graph is deleted

How many color choices are available for the graph pieces in Desmos?

• Five

• Four

• Three

• Six

What is the value of 'c' in the first set of equations used in the artwork?

• Zero

• Two

• One

• Negative one

What pattern is observed in the domain restrictions of the first set of equations?

• They are not mentioned

• They follow a specific pattern

• They vary randomly

• They are all the same

What happens to the graphs when additional equations are added to the artwork?

• They disappear

• They change color

• They shift and show vertical stretch or compression

• They remain unchanged

How are the additional six equations shifted in the expanded artwork?

• Down six units

• Up six units

• Right six units

• Left six units

What is the main purpose of creating artwork on the coordinate plane as mentioned in the conclusion?

• To learn about the behavior of different types of functions

• To create beautiful designs

• To compete with others

• To practice drawing skills
