Use the graph to determine a. open intervals on which the function is increasing, if any. b. open intervals on which the function is decreasing, if any C. open intervals on which the function is constant, if any

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
