okay we're going to graph this equation X is equal to negative y squared plus 4y as we can see we have the X by itself and we have this Y raised to the second power right there for the graph it's going to be a sideways parabola and notice that this right here it's in the standard form and let me write it down for you guys the standard form of the s...

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 yintercept?
To find the yintercept, set x=0 in the equation and solve for y.
Q: Can you explain the process of finding the yintercept 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 yintercept 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 yintercept is calculated by setting x=0, and key points on the graph are determined.
