What happens if a 0 in vertex form?

What happens if a 0 in vertex form?

The “a” value tells us the direction of the parabola’s opening. If a > 0 the parabola opens upwards, resulting in a minimum value. If a < 0 on the other hand, the parabola opens downwards, resulting in a maximum value.

What is the zero product property in quadratic equations?

Quadratic equations in factored form can be solved by using the Zero Product Property which states: If the product of two quantities equals zero, at least one of the quantities must equal zero. You can use the Zero Product Property to solve any quadratic equation written in factored form, such as (a + b)(a − b) = 0.

What is the vertex of a parabola if a 0?

In the graph, the highest or lowest point of a parabola is the vertex. The vertex of the graph of y=x2 is (0,0). If a>0 in f(x)=ax2+bx+c, the parabola opens upward. In this case the vertex is the minimum, or lowest point, of the parabola.

What is the quadratic function?

A quadratic function is one of the form f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero. The graph of a quadratic function is a curve called a parabola. A parabola intersects its axis of symmetry at a point called the vertex of the parabola. You know that two points determine a line.

What is the quadratic equation in vertex form?

The vertex form of a quadratic function is f(x) = a(x – h)2 + k, where a, h, and k are constants. of the parabola is at (h, k).

What does the zero product property tell us?

The zero product property states that if a⋅b=0 then either a or b equal zero.

How do you find the zeros and vertex of a quadratic function?

First find the zeros by any method (such as factoring or the Quadratic Formula). Find the x-coordinate of the vertex by averaging the zeros (add the zeros then divide by 2). Then, you can evaluate f(x) to find out the y-coordinate of the vertex. + 2x – 35.
