Domain: {x| x ≠ -4, x ∈ R} or (-∞,-4)∪(-4,∞)
Solving: your denominator cannot equal zero so solve this x + 4 ≠ 0

Range: (f(x) | f(x) ≥ 0} or [0, ∞)
Solving you can get zero because x = 0 gives you zero
but when you test other numbers in your domain like x = -2 and x = 2 you only get positive results. Therefore your range is all real non-negative numbers.

Write a problem that can be solved with a bar model that shows equal groups of liters

ioda

"In Grade 2 and early in Grade 3, students learned to use bar models to solve two-step problems involving addition and subtraction. This is extended in this chapter to include multiplication and division.

<span>Both multiplication and division are based on the concept of equal groups, or the part-part-whole concept, where each equal group is one part of the whole. In Grade 2, students showed this with one long bar (the whole) divided up into equal-sized parts, or units. This unitary bar model represents situations such as basket of apples being grouped equally into bags." </span>https://www.sophia.org/tutorials/math-in-focus-chapter-9-bar-modeling-with-multipli

How can you decompose the composite figure to determine its area?

laiz [17]

see the attached figure to better understand the problem

we know that

The Area of the composite figure is equal to the sum of Area 1, Area 2 and Area 3

The Area 1 is a triangle

The Area 2 is a rectangle

The Area 3 is equal a semicircle

therefore

<u>the answer is the option</u>
