What is the vertex of a quadratic function?

Back

Front

Find the vertex of the quadratic function: y = 4x^2 + 24x + 5

Back

The vertex is (-3, -31).

Front

What is the vertex of the parabola given by the equation y = x^2 + 4x + 3?

Back

The vertex is (-2, 1).

Front

What is the range of the function y = -2x^2 + 6x + 5?

Back

The range is y ≤ 6.

Front

What is the range of the function y = x^2 - 4?

Back

The range is y ≥ -4.

Front

What is the vertex of the quadratic function: x^2 + 10x + 24?

Back

The vertex is (-5, -1).

Front

How do you find the range of a quadratic function?

Back

To find the range, determine the vertex and the direction of the parabola (upward or downward). The range will be all values of y that the function can take.

Front

What does it mean if a parabola opens upwards?

Back

If a parabola opens upwards, the vertex is the minimum point, and the range is from the y-coordinate of the vertex to positive infinity.

Front

What does it mean if a parabola opens downwards?

Back

If a parabola opens downwards, the vertex is the maximum point, and the range is from negative infinity to the y-coordinate of the vertex.
