What is the vertex form of a parabola?

Back

The vertex form of a parabola is given by the equation f(x) = a(x - h)² + k, where (h, k) is the vertex of the parabola.

Front

How do you find the vertex of a parabola given its equation?

Back

To find the vertex of a parabola in the form f(x) = a(x - h)² + k, the vertex is the point (h, k).

Front

What is the process to convert a quadratic equation from standard form to vertex form?

Back

To convert from standard form ax² + bx + c to vertex form, complete the square.

Front

What does a negative 'a' value indicate in the vertex form of a parabola?

Back

A negative 'a' value indicates that the parabola opens downwards.

What does a vertical stretch by a factor of 2 mean for a function?

Back

A vertical stretch by a factor of 2 means that every y-coordinate of the function is multiplied by 2, making the graph taller.

Front

How do you find the inverse of a linear function?

Back

To find the inverse of a linear function f(x) = mx + b, swap x and y and solve for y.
