Parametric Functions Review

When eliminating the parameter, make sure and solve for "t" for the x-equation and then plug it in the y-equation and simplify.

x = 3 - t

y = -t +2

• y = x-3+2

• y = x-1

• y = x-5

When eliminating the parameter, make sure and solve for "t" for the x-equation and then plug it in the y-equation and simplify.

x = t²

y = 2t

• y = √x

• y = y/2

• y = 2√x

When eliminating the parameter, make sure and solve for "t" for the x-equation and then plug it in the y-equation and simplify.

x = √t

y = t - 3

• t = x²

• x = t²

• y = x² - 3

When eliminating the parameter, make sure and solve for "t" for the x-equation and then plug it in the y-equation and simplify.

x = t + 1

y = t - 1

• y = x -2

• y = x - 1

• x = t - 1
