MA1310 – Week 3 Lab Answer the following questions to complete this lab: 1. State in a few words, what is an exponential function? * Functions whose equations contain a variable in the exponent. 2. What is the natural exponential function?
Carlos Gomez MA1310 12/30/2014 MA1310: Module 2 Exponential and Logarithmic Functions Exercise 2.1 Exponential and Logarithmic Functions Answer the following questions to complete this exercise: 1. What is an exponential function? It is a function whose value is a constant raised to the power of the argument, especially the function where the constant is e. 2. What is a natural exponential function? It is used to model a relationship in which a constant change in the independent variable gives the same proportional change in the dependent variable.
Lab 1 This lab exercise covers: * an introduction to C programming * arithmetic statements * Standard input output * Mathematical functions Exercise 1.1 Write a program that prints the string “Computing Systems & Programming” to the screen, reads an integer from the keyboard, and print the integer to the screen. Exercise 1.2 Write the following program. Compile, link and run it. #include<stdio.h> int main () { int year; float height; year = 21; height = 1.77; printf("Ali is %d years old and %f meter height\n", year, height); return 0; } Exercise 1.3 Write a program that demonstrates the use of the +,-,* and / operators for integers. Type the following program.
Composition and Inverse Functions MAT 222: Intermediate Algebra Instructor October 12, 2014 Composition and Inverse Functions Functions are helpful in algebra to determine model dependencies among different variables. For example, some situations require many levels of dependencies and are useful to express the final variable in terms of the first variable. Function composition defines a variable in terms of another one while reducing the level of dependencies; and an inverse function comes into play when checking a correlation between dependent and independent variables. This paper will outline and solve a true composition and inverse function. The functions are: fx=2x+5 gx=x2-3 hx=7-x3
