Understanding Parabolas

The video provides an introduction to parabolas, covering key vocabulary such as x-intercepts, roots, and solutions. It explains the concepts of minimum and maximum points, the axis of symmetry, and the vertex. The video aims to familiarize students with these terms and their applications in graphing parabolas.

What is the primary direction in which a downward-opening parabola faces?

• Downward

• Sideways

• Upward

• Horizontally

Which of the following is NOT a term used to describe x-intercepts in parabolas?

• Roots

• Zeros

• Peaks

• Solutions

If a parabola opens upward, what can be said about its solutions?

• It has one solution

• It has infinite solutions

• It has two solutions

• It has no solutions

In the context of parabolas, what does the term 'maximum' refer to?

• The highest point on the x-axis

• The lowest point on the x-axis

• The lowest point on the y-axis

• The highest point on the y-axis

What is the minimum value of the red parabola discussed in the video?

• Negative three

• Positive two

• Positive one

• Zero

What does the axis of symmetry represent in a parabola?

• The line that runs parallel to the x-axis

• The point where the parabola reaches its maximum

• The point where the parabola intersects the x-axis

• The line that divides the parabola into two equal halves

For the green line, what is the x-coordinate of the axis of symmetry?

• x = -4

• x = 0

• x = -2

• x = 4

What is the term used for the point that provides both the maximum or minimum and the axis of symmetry in a parabola?

• Intercept

• Vertex

• Root

• Focus

In the context of parabolas, what are the coordinates of the vertex typically labeled as?

• m and n

• h and k

• x and y

• a and b

What does the 'k' value in the vertex of a parabola indicate?

• The slope of the parabola

• Whether the parabola has a maximum or minimum

• The x-intercept of the parabola

• Whether the parabola opens left or right
