What does it mean for y to be a function of x?

Back

For y to be a function of x, each input x must correspond to exactly one output y. This means that no x-value can map to more than one y-value.

Front

How do you perform a dilation on a geometric figure?

Back

To dilate a figure, multiply the coordinates of each vertex by the scale factor. For example, if the scale factor is 3, the coordinates (x, y) become (3x, 3y).

What are the coordinates of a triangle's vertices after dilation by a scale factor of 3 from the origin?

Back

If the original vertices are (2,0), (3,-1), and (-2,-5), the new vertices after dilation are (6,0), (9,-3), and (-6,-15).

Front

What is the definition of a scale factor in dilation?

Back

The scale factor is a number that scales, or multiplies, the dimensions of a figure. A scale factor greater than 1 enlarges the figure, while a scale factor between 0 and 1 reduces it.
