of data “by reference.” When a piece of data is passed “by value” the piece of data remains the same. If the value is the number “5” it will always pass the value of 5. However if the piece of data is passed “by reference” the value stored in the variable passed by reference can change depending on what the program is trying to do. This is useful for programmers if they are creating a program to multiply a user input number by a specific number. Say the user inputs the number “10” that is passed by

philosophy allowed for major contributions to the modern world‚ with major impact. Multiplying a variable forms the basis for algebra. The unknown number can represent anything. A Muslim mathematician by the name of Al-Khwarizmi wrote a book in the 800’s about Algebra and his findings. Algebra is the basis for most mathematical processes and with out it there would be no way to find an unknown variable. This also allowed for the basis of astronomy. Astrological maps were formed with algebra and a

Determine whether the equation defines a function with independent variable x. If it does‚ find the domain. If it does not‚ find a value of x to which there corresponds more than one value of y. x|y| = x + 9 This is not a function. When x=3‚ there are two values of y‚ -4 and 4 2.

this graph‚ the line should touch the origin because it is a positive slope going from lower values to higher values. Also it passes through the origin because direct variation relationships are in the form of y = mx‚ where y and m are constant variables. For the absorbance value to zero‚ the concentration must be also be zero. Should the line of Concentration versus Absorbance go through the origin? As stated above‚ the line should touch and go through the origin eventually because it is a
