Questions & Answers

Q: How do you graph a sideways parabola?

To graph a sideways parabola, you need to use the standard form equation and find the vertex, which can be calculated using the vertex formula (-B/2A).

Q: What does a negative A value in the equation indicate?

A negative A value in the equation of a sideways parabola means that the parabola opens to the left.

Q: How do you find the y-intercept?

To find the y-intercept, set x=0 in the equation and solve for y.

Q: Can you explain the process of finding the y-intercept in more detail?

By setting x=0 in the equation, you can factor out y and solve for the two values of y that will give you the y-intercept points.

Summary & Key Takeaways

  • The video explains how to graph a sideways parabola using the equation in standard form.

  • The vertex formula is used to find the vertex of the parabola.

  • The y-intercept is calculated by setting x=0, and key points on the graph are determined.
