Atransformation that increases or decreased the size of a figure according to the scale

Dilation

Step-by-step explanation

In geometry, a transformation that enlarges or reduces a polygon by a certain scale factor around a particular center point is called dilation. A scale factor is the amount by which an image grows or shrinks .In this case, dilution requires us to multiply initial dimensions by the scale factor to obtain the dimensions of the image.

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
