What is the vertex form of a quadratic function?

Back

Front

What is the axis of symmetry for a quadratic function?

Back

Front

How do you determine if a quadratic opens upwards or downwards?

Back

A quadratic function opens upwards if the coefficient 'a' is positive and downwards if 'a' is negative.

Front

What is the standard form of a quadratic function?

Back

Front

What does the absolute value function represent graphically?

Back

The absolute value function represents a V-shaped graph that opens upwards, reflecting all negative values to positive.

Front

How do you find the y-intercept of a function?

Back

To find the y-intercept of a function, set x = 0 and solve for f(0).

Front

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

Back

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

Front

What is the effect of changing the value of 'h' in the vertex form of a quadratic?

Back

Changing 'h' shifts the graph horizontally. If 'h' increases, the graph shifts to the right; if 'h' decreases, it shifts to the left.

Front

What is the effect of changing the value of 'k' in the vertex form of a quadratic?

Back

Changing 'k' shifts the graph vertically. If 'k' increases, the graph shifts up; if 'k' decreases, it shifts down.

Front

How do you identify the transformations of a function from its equation?

Back

Transformations can be identified by observing changes in the function's equation, such as shifts (horizontal/vertical), reflections, and stretches/compressions.
