Desmos and Quadratic Functions Quiz

What is the primary point of interest when finding the minimum or maximum of a quadratic function?

• The axis of symmetry

• The vertex

• The y-intercept

• The x-intercept

In Desmos, what should you do if you cannot immediately see the vertex of a quadratic function?

• Switch to a different graphing tool

• Adjust the equation

• Zoom out using the scroll wheel

• Change the color of the graph

When a question asks for the minimum value of a function without specifying x, what value should you provide?

• The y-coordinate of the vertex

• The x-coordinate of the vertex

• The axis of symmetry

• The slope of the function

What is the vertex of the function f(x) = 4x^2 - 50x + 126?

• (6.25, -30.25)

• (7, -27)

• (12.5, -50)

• (0, 126)

What should you be cautious of when selecting the x or y value in a question?

• The color of the graph

• The size of the graph

• The type of function

• The phrasing of the question

How can you perform a function transformation in Desmos?

• By changing the graph's color

• By adjusting the graph's scale

• By typing the transformation directly into Desmos

• By using a separate transformation tool

For the function g(x) = f(x) + 5, where f(x) = 4x^2 + 64x + 262, what is the x-coordinate of the vertex?

• 0

• 7

• 6.25

• -13

What is the maximum value of the function y = -2x^2 + 3 + 6x?

• 1.5

• 7.5

• 3

• 0

When finding the maximum of a downward-facing parabola, what value is considered the maximum?

• The axis of symmetry

• The slope of the parabola

• The y-coordinate of the vertex

• The x-coordinate of the vertex

What is the process to find the maximum of a downward-facing parabola in Desmos?

• Change the graph's color

• Zoom in until the vertex is visible

• Click on the graph once

• Click on the graph twice
