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?
