What is the equation for the axis of symmetry of a parabola?

What is the standard form of a quadratic function?

What is the vertex of a parabola?

Front

How do you find the low point of a quadratic function?

Back

The low point (minimum) of a quadratic function occurs at the vertex if the parabola opens upwards. Use the vertex formula to find the coordinates.

What is the formula for the axis of symmetry in a quadratic function?

Back

Front

What does the 'a' value in a quadratic function indicate?

Back

The 'a' value determines the direction of the parabola: if 'a' is positive, the parabola opens upwards; if 'a' is negative, it opens downwards.

Front

What is the significance of the 'b' value in a quadratic function?

Back

The 'b' value affects the position of the vertex along the x-axis and influences the axis of symmetry.

Front

What is the y-intercept of a quadratic function?

Back

Front

How can you determine if a quadratic function has a maximum or minimum value?

Back

If 'a' is positive, the function has a minimum value at the vertex; if 'a' is negative, it has a maximum value at the vertex.

Front

What is the general shape of a quadratic function's graph?

Back

The graph of a quadratic function is a parabola, which can open upwards or downwards.
