Graph each pair of parametric equations on your calculator. Sketch the result and use arrows to indicate the direction of increasing t-values along the graph. Limit your t-values as indicated, or, if an interval for t isn't listed, then find one that shows all of the graph that fits in a friendly window with a factor of 2.
a. x = 3t - 1
y = 2t + 1
b. x = t + 1
y = t2
c. x = t2
y = t + 3
-2 ( t ( 1
d. x = t - 1
y = (4 - t2
-2 ( t ( 2
