Red oak trees grow at a rate of about 2 feet per year. you buy and plant two red oak trees, one that is 6 feet tall and one that is 8 feet tall. the height h (in feet) of the shorter tree can be modeled by h = 2t + 6 where t is the time (in years) since you planted the tree. the height of the taller tree can be modeled by h = 2t + 8. a. graph both equations in the same coordinate plane. b. use the graphs to find the difference of the heights of the trees 5 years after you plant them. what is the difference after 10 years? what do you notice about the difference of the heights of the two trees?
