Which graph is defined by the function f(x) = ` | | ` x ` | | ` if 0 is less that or equal to x and x is less than or equal to 4 (where ` | | ` x ` | | ` is the greatest integer function, i. e., the greater integer less than or equal to x)?

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400
