Graph the curve whose parametric equations are given.
- $$\begin{array} { l } C _ { 1 } : x = 7 \sin t , y = 7 - 7 \cos ^ { 2 } t ; \frac { \pi } { 2 } \leq t \leq \frac { 3 \pi } { 2 } \\C _ { 2 } : x = \ln t , y = \ln t ^ { 2 } ; e ^ { - 4 } \leq t \leq e ^ { 3 } \\C _ { 3 } : x = t ^ { 2 } - 8 , y = t - 3 ; - 4 \leq t \leq 4 \\C _ { 4 } : x = t - 5 , y = t + 2 ; - 4 \leq t \leq 7\end{array}$$
