This question is from multivariable calculus assignment.


Are the following statements true or false?

1. The parametric curve with equations x=(3t+4)^2, y=5(3t+4)^(2)-9, for 0<=t<=3 is a line segment.
   
2. A parameterization of the graph of y=ln(x) for x>0 is given by x=e^t, y=t for -inf
   

I know the answers are True for both questions but how do you find out?


Thanks!
