Graphing Quadratics in Vertex Form: Practice Challenges

Mrs. Shores provides a quick tutorial on graphing quadratic functions in vertex form, focusing on IXL bb5 assignment. She explains how to find the vertex of a function, even if it's not initially in vertex form, and demonstrates graphing with examples. The video concludes with contact information for further assistance.

What is the main topic of today's assignment?

• Solving systems of equations

• Factoring polynomials

• Graphing quadratic functions in vertex form

• Solving linear equations

What is the general form of a quadratic function in vertex form?

• y = a(x + h)^2 + k

• y = ax^2 + k

• y = ax^2 + bx + c

• y = a(x - h)^2 + k

In the vertex form y = a(x - h)^2 + k, what do 'h' and 'k' represent?

• The y-intercepts

• The vertex coordinates

• The x-intercepts

• The coefficients of x

How can you rewrite the function y = 8x^2 to identify its vertex?

• y = 8(x - 1)^2 + 1

• y = 8(x + 0)^2 - 0

• y = 8(x - 0)^2 + 0

• y = 8(x - 2)^2 + 2

What is the vertex of the function y = 8x^2?

• (1, 8)

• (0, 0)

• (8, 0)

• (0, 8)

If a quadratic function has a positive coefficient, in which direction does the parabola open?

• To the right

• To the left

• Upwards

• Downwards

For the function y = -5x^2, what is the vertex?

• (5, 0)

• (0, -5)

• (1, -5)

• (0, 0)

How do you determine the direction in which a parabola opens?

• By the x-intercepts

• By the value of 'k'

• By the value of 'h'

• By the sign of the coefficient 'a'

What is the vertex of the function y = 2x^2 - 8?

• (2, 0)

• (2, -8)

• (0, -8)

• (0, 2)

What is the goal for today's assignment on the IXL platform?

• Complete all problems

• Reach a score of 80

• Reach a score of 50

• Finish within an hour
