Which vаlue is а multiple rооt оf the polynomiаl shown in the graph have? The x-axis spans from negative 10 to 10, and the y-axis spans from below 0 to above 40. The x-axis has a scale of 5 in increments of 1 and the y-axis has a scale of 20 in increments of 5. The red polynomial function has a local minimum around (negative 3, 0) and a local maximum near (1.5, 50). The function starts from positive infinity, decreases to the local minimum, rises to the local maximum, and then falls towards negative infinity, extending out of view at both ends.
