What is simple closed figure

Simple Closed Figure :

In simple closed curves the shapes are closed by line-segments or by a curved line.

Ex: Triangle, quadrilateral, circle, etc

(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

table 3 represents a direct variation function. : )
