Mathematics

Neporo4naja [7]3 years ago

Answer:

−4  is an expansion; 2.5  is an expansion; 2/3  is a contraction; and −3/4 is a contraction.

Step-by-step explanation:

In a dilation, a scale factor greater than 1 or less than -1 is an expansion.  It will make the figure larger.  This means that -4 is an expansion, since it is less than -1, and 2.5 is an expansion, since it is greater than 1.

A scale factor that is greater than -1 but less than 1 will be a contraction.  It will make the figure smaller.  This means that 2/3 is an expansion, since it is less than 1, and -3/4 is a contraction, since it is greater than -1.

What is the minimum value for the function shown in the graph?<br><br> Enter your answer in the box.
Fudgin [204]

The minimum value is the lowest point of a graphed line. The would be the bottom of the "U" shape.

Looking at the graph you can see that the bottom of the U is touching the horizontal line at x = -5.5, so this would be the minimum value.

The lowest part of the line is at -5.5
