Thank you for the opportunity to help you with your question!
The vertex of a quadratic equation is the highest or lowest point of that equation. It lies on the plane of symmetry of the entire parabola as well; whatever lies on the left of the parabola is a complete mirror image of whatever is on the right. If you want to find the vertex of a quadratic equation, you can either use the vertex formula, or complete the square.
1.Identify the values of a, b, and c. In a quadratic equation, the x2 term = a, the x term = b, and the constant term (the term without a variable) = c.
2.Use the vertex formula for finding the x-value of the vertex.
The vertex is also the equation's axis of symmetry. The formula for
finding the x-value of the vertex of a quadratic equation is x = -b/2a. Plug in the relevant values to find x. Substitute the values for a and b.
This was because the questions were many and involving but the time period was very short.
I can now answer them, both 3 and 4.
4. by finding the intercept values of x and y, you will be able to interprate the nature of the graph.
