Front

What is the vertex of a quadratic function?

Back

The vertex is the highest or lowest point of the parabola, representing the maximum or minimum value of the function.

Front

How do you find the quadratic function passing through three points?

Back

Front

What does it mean to solve an equation by factoring?

Back

It means to express the equation as a product of its factors, allowing you to find the values of the variable that make the equation true.

Front

How do you determine the maximum height of a projectile?

Back

The maximum height can be found at the vertex of the quadratic function that models the projectile's height over time.

Front

What is the standard form of a quadratic function?

Back

Front

What is the difference between the vertex and the x-intercepts of a quadratic function?

Back

The vertex is the highest or lowest point of the parabola, while the x-intercepts are the points where the graph crosses the x-axis.

Front

How do you find the time it takes for an object to reach its maximum height?

Back

You can find the time by determining the x-coordinate of the vertex of the quadratic function that models the object's height.
