Hi, please help me with these questions I have here. Can you show the steps or the work as well thank you. PLEASE ANSWER BOTH PLEASE THANK YOU

Question 17: (1 point) Letr(t) =28+ 1 Find corresponding parametric equations. 313" 1 x=2, y= 313 1 с *= 3, y=2+2 3:31 c=21 1 y = 32 y = 213 312 Question 18: (1 point) The position of a particle at the time t is given parametrically by y=+and x = (2-31). Show that the particle crosses the y-axis three times. The particle crosses the y-axis when x = 1. That occurs at i = -2.0, and/2. The particle crosses the y-axis when x = 1. That occurs at t = - 3.0, and/3. The particle crosses the y-axis when x = 0). That occurs at t = - 2.0, and/2. The particle crosses the y-axis when x= -1. That occurs at t= - V2.0, and/2. The particle crosses the Y-axis when x = 0. That occurs at t = - 3.0, and/3. The particle crosses the y-axis when X=- 1. That occurs at (= - 3.0, and/3. 0 0
