Creating Quadratic Function

What is the formula for finding 'A' in a quadratic function?

• A = (First difference/2)

• A = (Second difference/2)

• A = (Sum of differences/2)

• A = (Product of differences/2)

What is the first step in solving a quadratic function using Desmos?

• Input the values into Desmos table.

• Click on the blue Regression Icon.

• Type in table into Desmos to bring up the table.

• Choose 'Quadratic Regression' from the drop-down.

When creating an explicit Quadratic equations by hand What is done in Step 5 of the process?

• Write the equation in the form f(x) = Ax² + Bx + C

• Solve for A

• Read the quadratic equation

• Substitute values into the equation

Create the explicit quadratic equation of the given table.

• 
• 
• 
• y=-1x²-4x+5

What is the role of the y-intercept in a quadratic function?

• It determines the slope of the function.

• It is the point where the graph crosses the y-axis.

• It is the maximum point of the function.

• It is the minimum point of the function.

When writing a explicit quadratic equations by hand What is the unknown coefficient solved for in Step 4?

• A

• B

• C

• f(1)

What is the vertex of this function?

• (0, -3)

• (1, -4)

• (-2, 5)

• {-1, 3}

y = -(x + 1)² - 4 y = -(x + 1)² + 4 y = -(x - 1)² - 4 y = (x + 1)² + 4

• y = -(x + 1)² - 4

• y = -(x + 1)² + 4

• y = -(x - 1)² - 4

• y = (x + 1)² + 4
