The functions $f(t)$ and $g(t)$ are shown below.

If the motion of a particle whose position at time $t$ is given by $x=f(t)$, $y=g(t)$, sketch a graph of the resulting motion and use your graph to answer the following questions:

(a) The slope of the graph at $\left(0.25,-0.5\right)$ is
(enter undef if the slope is not defined)

(b) At this point the particle is moving neither left nor right to the left to the right and neither up nor down up down .

(c) The slope of the graph at $\left(1.75,-0.5\right)$ is
(enter undef if the slope is not defined)

(d) At this point the particle is moving neither left nor right to the left to the right and neither up nor down up down .
