Question

Let {(z) - 2 + 1 2 Instructions: Draw a sign chart on a piece of paper and then list each interval below using the format [left endpoint, right endpoint, above or below) indicating the starting and ending points of the interval and whether the graph is above or below the s-axis over that interval. Use square brackets and separate your entries by commas. Use infty for too and -infty for - 00 Examples: • (-1,0, above) means that the graph is above the z-axis over the interval from-1 to 0. • (-infty, -4, below) means that the graph is below the s-axis to the left of -4
