It seems like the actual equations for each question are missing, so I'll need that information to solve these questions for you.

Once you provide the equations, I can help determine the y-intercept, vertex, x-intercept, and other related points accurately. Could you provide them?

Here are five related questions to help you think more about this topic:

1. How do you determine the y-intercept of a quadratic equation in standard form?
2. What is the formula to find the x-coordinate of the vertex in a quadratic function?
3. How do you find the x-intercepts (if they exist) for a quadratic equation?
4. How does the discriminant of a quadratic equation affect the x-intercepts?
5. What is the relationship between the vertex and the axis of symmetry of a parabola?

Tip: For any quadratic equation in the form $y = ax^2 + bx + c$, the y-intercept is simply $c$, and the x-coordinate of the vertex is given by $x = -\frac{b}{2a}$.
