What is the vertex form of a quadratic equation?

Back

Front

How does vertical stretching affect the graph of a quadratic function?

Back

Vertical stretching by a factor of 'a' (where a > 1) makes the parabola narrower, while a factor of 'a' (where 0 < a < 1) makes it wider.

Front

What is the effect of shifting a quadratic function to the right?

Back

Shifting a quadratic function to the right by 'h' units changes the vertex from (h, k) to (h + d, k), where d is the number of units shifted.

Front

What is the effect of shifting a quadratic function down?

Back

Shifting a quadratic function down by 'k' units changes the vertex from (h, k) to (h, k - d), where d is the number of units shifted.

Front

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

Back

Front

How do you find the vertex of a quadratic function given in standard form?

Back

Front

What does the range of a quadratic function indicate?

Back

The range of a quadratic function indicates the set of possible output values (y-values) that the function can produce, which depends on the direction of the parabola (upward or downward).

Front

What is the significance of the vertex in a quadratic function?

Back

The vertex of a quadratic function represents the maximum or minimum point of the parabola, depending on whether it opens upwards or downwards.

Front

How do you determine if a quadratic inequality is represented by a shaded region above or below the curve?

Back

Front

What is the relationship between the coefficients of a quadratic function and its graph?

Back

The coefficient 'a' determines the direction of the parabola (upward if a > 0, downward if a < 0) and its width (narrower for larger |a|, wider for smaller |a|).
