The area, A, in square feet, of a rectangular storage bin in a warehouse is given by the function A(x) = x2 - 6x, where x is the width, in feet, of the storage bin.


Part A: Based upon this function, which statement would be true? Show your work or explain how you found the solution.


The x-intercepts of the function are 3 and -9, which are a lower bound and an upper bound for the possible values of the length of the storage bin.


The x-intercepts of the function are 3 and -9, which are a lower bound and an upper bound for the possible values of the width of the storage bin.


The x-intercepts of the function are 0 and 6, which are a lower bound and an upper bound for the possible values of the length of the storage bin.
