Question

What is the orientation of the plane curve?

Answer 1

Answer: -up to the right and down to the right at the same time


Explanation:

1) The curve is given by its parametric equations: 

x = t² - 4t
y = t - 2


2) You can solve that curve by eliminating the parameter t and so draw the curve.

Nevertheless, it is not necessary as the graph is also given.

3) The graph shows that the curve goes up to the right and also down to the right. This is, as x grows from x = - 4 the curve has to branches one goes up and the other goes down, so the answer is -up to the right and down to the right at the same time
