The following graph is a translation of the graph of one of the basic functions defined by y=x, y=x. y=x, or y=|x. Find the equation that defines the function. Then, determine the largest open interval of the domain over which the function is (a) increasing and (b) decreasing. 10042 CHIK The equation of the function is (Type an equation.) (a) Find the largest open interval of the domain over which the function is increasing A. The open interval is (Type your answer in interval notation.) B. There is no open interval of the domain over which the function is increasing (b) Find the largest open interval of the domain over which the function is decreasing. OA. The open interval is (Type your answer in interval notation.) B. There is no open interval of the domain over which the function is decreasing.
