question 188

Multiple Choice

Give two parametric representations for the equation of the parabola.
- $$y = x ^ { 2 } - 8 x + 25$$

• A) \(x = t , y = t ^ { 2 } + 8 t + 25\) for \(t\) in \(( - \infty , \infty ) ; x = t - 4 , y = t ^ { 2 } + 9\) for \(t\) in \(( - \infty , \infty )\)
• B) \(x = t , y = t ^ { 2 } - 8 t - 25\) for \(t\) in \(( - \infty , \infty ) ; x = t - 4 , y = t ^ { 2 } - 9\) for \(t\) in \(( - \infty , \infty )\)
• C) \(x = t , y = t ^ { 2 } + 8 t + 25\) for \(t\) in \(( - \infty , \infty ) ; x = t - 4 , y = t ^ { 2 } - 9\) for \(t\) in \(( - \infty , \infty )\)
• D) \(x = t , y = t ^ { 2 } - 8 t + 25\) for \(t\) in \(( - \infty , \infty ) ; x = t - 4 , y = t ^ { 2 } + 9\) for \(t\) in \(( - \infty , \infty )\)
