Recall that the perimeter of a square is 4 times as large as the length of one of the sides of the square. Let x represent the length of one side of a square (in inches), and let y represent the perimeter of that square (in inches). a. y is a function of x, so we can define a function f to represent this relationship (e.g., f(x) = y). Write a function formula for the function f. Preview b. What is the (practical) domain of the function f? Enter your answer as an inequality. Preview c. What is the (practical) range of the function f? Enter your answer as an inequality. Preview

Sequence and Series

A sequence is defined as a collection of things. Series is defined to sum the things one by one in the sequence.  It was invented by German mathematician Carl Friedrich Gauss.
