question 82

Multiple Choice

Find two sets of parametric equations for the given rectangular equation.
- $$y = x ^ { 2 } - 4$$

• A) \(x = t , y = t ^ { 2 } - 4 ; x = \sqrt { t } , y = t - 4 , t \geq 0\)
• B) \(x = t , y = t ^ { 2 } - 4 ; x = \sqrt { t } , y = t + 4 , t \geq 0\)
• C) \(x = - t , y = t ^ { 2 } + 4 ; x = \sqrt { t } , y = t - 4\)
• D) \(x = - t , y = t ^ { 2 } - 4 ; x = \sqrt { t } , y = - t + 4 , t \geq 0\)
