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.
