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...

### 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.
