Whаt is the аpprоximаte value оf the ( y )-intercept? The x-axis spans frоm below negative 5 to 5, and the y-axis spans from below negative 20 to above zero. The x-axis has a scale of 5 in increments of 1 and the y-axis has a scale of 10 in increments of 2. The red curve represents a polynomial function with four turning points. It begins from the bottom-middle of the third quadrant, reaches a local maximum at (negative 3, 0), then drops steeply to a local minimum near (negative 1.5, negative 21). It rises again to another local maximum near (0.5, 0.8), falls to a local minimum around (1, 0), and then steeply extends upward out of view.
