How do you represent a function using a graph?

Back

A function can be represented on a graph where the x-axis represents the input values and the y-axis represents the output values. A vertical line test can be used to determine if a graph represents a function.

What is dilation in geometry?

Back

Dilation is a transformation that changes the size of a figure but not its shape, using a center of dilation and a scale factor.

What is the scale factor in dilation?

Back

The scale factor is the ratio of the size of the image to the size of the original figure. A scale factor greater than 1 enlarges the figure, while a scale factor between 0 and 1 reduces it.
