Find the open interval(s) where the following function is increasing, decreasing, or constant. Express your answer in interval notation. x 10 5 5 10 y 10 5 5 10 Cartesian Coordinate PlaneThe horizontal axis is labeled with x. The horizontal axis contains 21 grid lines, starts at -10, and ends at 10; and the axis is labeled with the values: -10, -5, 5, 10.The vertical axis is labeled with y. The vertical axis contains 21 grid lines, starts at -10, and ends at 10; and the axis is labeled with the values: -10, -5, 5, 10.Function uA solid horizontal line is drawn with the equation u(x)=4 which is neither increasing nor decreasing
