Sketch the curve of x(t) = 2t + 1 and y(t) = t² + 2.

• A
• B
• C
• D

Write x = 2t  and y = t² + 3  in rectangular form .

• y = 4x²  + 3
• y = ¼ x² + 3
• y = 4t² + 12
• y = (x - 2)² + 3

Find the point based on the parametric equations. t = 3

x = 1 - 2t

y = 4t + 1

• (-5, 13)

• (13, -5)

• (5, 13)

• (13, 5)

Which set of parametric equations satisfies the given data table?

• x(t) = t³ - 1

  y(t) = 2t

• x(t) = t³ - 1

  y(t) = t + 2

• x(t) = t + 8

  y(t) = t + 2

• x(t) = t + 8

  y(t) = 2t

Eliminate the parameter

x = 3/t

y = 6t + 1

• y = (18/x) + 1

• y = 18x + 1

• y = 19x

• y = 19/x

Eliminate the parameter.

x= √t and y=5t

• y=5x²

• y=5x

• y= x - 5

• y=x²
