Two objects E and F are traveling by the following parametrically defined functions
x = 2t - 4 x = 2ty = t - 1 y = t + 1
a. If the paths of the objects E and F intersect at (6,4), at what time do they intersect if the parameter t stands for time?
b. Write an equation d(t) that represents the distance between the two objects E and F at any point in time. Graph d(t).
c. What do you notice about the graph of d(t)? What does this tell us about the objects E and F?
