What is function transformation?

Function transformation involves altering the shape, position, or orientation of a function's graph. This can include vertical and horizontal shifts, reflections, stretching or compressing, and more. By applying these transformations, one can manipulate the appearance and behavior of the function without changing its underlying equation, enabling a deeper understanding of how different factors affect the function's output.

What is the role of the parent function in function transformation?

The parent function serves as the base function that undergoes transformations such as translations, reflections, stretches, or compressions to create new functions. By applying shifts in position, changes in size, and flips across a line, the parent function can be diversified to generate a wide range of functions with different characteristics while still preserving some of the original properties. Ultimately, the parent function acts as a reference point from which transformed functions are derived, showcasing the impact of various modifications on the function's graph and equation.

How does changing the sign of the function affect its transformation?

Changing the sign of a function reflects it across the x-axis, causing all y-values to become their opposite. This transformation essentially flips the function vertically and reverses its direction, so points that were initially above the x-axis will now be below it, and vice versa.

What happens when the function is horizontally translated?

When a function is horizontally translated, the entire graph of the function shifts left or right along the x-axis by a certain amount. This means that all the points on the graph will move horizontally without changing their vertical positions. The equation representing the function is modified by adding or subtracting a value inside the function, which affects the x values of the points on the graph.

How does vertically translating a function impact its graph?

Vertically translating a function shifts the entire graph of the function up or down by a certain amount. If the translation is upward, the graph moves vertically upward, whereas if the translation is downward, the graph moves vertically downward. This vertical shift does not affect the shape or orientation of the function's graph, but rather changes its position on the coordinate plane.

What occurs when a function is reflected over the x-axis?

When a function is reflected over the x-axis, all the y-coordinates of the points on the function are negated. This means that any point (x, y) on the original function gets reflected to (x, -y) on the new function after the reflection. This operation results in the function being flipped upside down in relation to the x-axis.

How is the graph affected when the function is reflected over the y-axis?

When a function is reflected over the y-axis, each point's x-coordinate is multiplied by -1 while the y-coordinate remains the same. This reflection causes the graph to be a mirror image of the original graph across the y-axis, essentially flipping it horizontally. Points that were to the right of the y-axis in the original graph will now be to the left after reflection, and vice versa.

What happens when a function is horizontally stretched or compressed?

When a function is horizontally stretched, it means that the graph of the function is widened along the x-axis, making it appear more spread out. This occurs because each x-value on the graph is multiplied by a constant greater than 1, which results in a scaling effect that stretches the function horizontally. Conversely, when a function is horizontally compressed, it means that the graph is narrowed along the x-axis, making it appear more condensed. This is done by multiplying each x-value on the graph by a constant between 0 and 1, which results in a scaling effect that compresses the function horizontally.

How does vertically stretching or compressing a function change its graph?

Vertically stretching a function results in the graph being elongated vertically, making the curve steeper or more vertically expansive. Conversely, vertically compressing a function compresses the graph vertically, making the curve shallower or more vertically condensed. This change is achieved by multiplying the function by a constant greater than 1 for stretching or between 0 and 1 for compressing.

What occurs when the function is rotated around the origin?

Rotating a function around the origin will result in a transformation that changes the orientation of the function with respect to the coordinates system. The rotated function will essentially be a rotated version of the original function in the plane.
