1. An ecologist is studying a forest with a mixture of tree types. Since the average tree height in the area is 40 feet, he measures the height of the tree against that. He also
graph. Is there evidence of an association between tree height and tree type? Explain
your reasoning
records the type of tree. The results are shown in the table and segmented bar

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
