Composition and Inverse
The assignment paper for this week is to define the following functions of Elementary and Intermediate Algebra: Problem number 1) fx=2x+5, Problem number 2) gx=x2- 3, and Problem number 3) hx= 7-x3. Compute (f – h)(4).

Evaluate the following two compositions: and .
Transform the g(x) function so that the graph is moved 6 units to the right and 7 units down. Find the inverse functions and .
1. Write a two to three page paper that is formatted in APA style and according to the Math Writing Guide. Format your math work as shown in the example and be concise in your reasoning. In the body of your essay, please make sure to include: * Your solutions to the above problems, making sure to include all mathematical work for both problems, as well as explaining each step. * A discussion of the applicability of functions to the real world, based upon your reading of Chapter 11 of Elementary and Intermediate Algebra. Be sure to use specific examples, a brief discussion of why your examples are important, and to cite your sources. The paper must be at least two pages in length and formatted according to APA style. Cite your resources in text and on the reference page. For information regarding APA samples and tutorials, visit the Ashford Writing Center, within the Learning Resources tab on the left navigation toolbar.

Composition and Inverse
We are working with the following functions:
f(x) = 5x – 3 g(x) = x2 + 2 h(x) = 3 + x
7
We have been asked to compute (f – h)(4).
(f – h)(4) = f(4) – h(4) So we can evaluation each separately and then subtract.
f(4) = 5(4) – 3
= 20 – 3 = 17 f(4) = 17
h(4) = (3 + 4)/7
= 7/7 = 1 h(4) = 1
(f – h)(4) = 17 – 1 = 16 This is our answer.
Next we are to compose two pairs of the functions into each other. First we will...

This week we have been assigned three functions which we must evaluate. These are the functions which we have to evaluate this week.
fx=2x+3 gx=x2-3 hx=7-x3
We have been asked to compute(f-h)(4).
So we can evaluate each separately and then subtract.
f-h4=f4-h(4)
f4=24+3
=8+3=11 f4=11
h4=7-43
=33=1 h4=1
This is our final answer.
f-h4=11-1=10
Next we are...

Composition and Inverse
The following functions will be used in this week’s assignment.
1. fx=2x+5
2. gx=x2-3
3. hx=7-x3
We are first asked to compute f-h4. Like many algebra problems, the solution becomes obvious, or at least easier, once it has been rewritten into a different format. We will solve the problem in this way:
f-h(4) - Original expression
f4-h4 - Rewritten...

Single Parent Families
Single parenting has several effects on both the children and the parent. These can include the risk, from the quality of parenting to the exposure of stress; the advantages, from the confidence of both the child and parent to the strong bond they have with each other; and the disadvantages, from the poor financial status to the effects that take place for both the child and the parent. These...

* Horizontal line test – a function is one-to-one if every horizontal line intersects the graph of the function at most once
* Examples: Determine whether the following functions are one-to-one
