(Alg.2) 4.1 Graphing Quadratics Functions.

Front

What is the standard form of a quadratic function?

Back

Front

What does the coefficient 'a' in a quadratic function determine?

Back

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

Front

What is the vertex of a parabola?

Back

The vertex of a parabola is the highest or lowest point on the graph, depending on the direction it opens.

Front

How do you find the x-coordinate of the vertex of a quadratic function in standard form?

What is the axis of symmetry in a quadratic function?

Front

What is the significance of the discriminant in a quadratic equation?

Back

Front

What is the low point of a parabola that opens upwards called?

Back

The low point of a parabola that opens upwards is called the minimum.

Front

What is the high point of a parabola that opens downwards called?

Back

The high point of a parabola that opens downwards is called the maximum.

Front

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

Back

The graph of a quadratic function is a U-shaped curve called a parabola.

Front

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

Back

You can determine if a quadratic function has a maximum or minimum by looking at the sign of the coefficient 'a': if 'a' is positive, it has a minimum; if 'a' is negative, it has a maximum.
