Consider the following parametric equation. x equals (t plus 5 )squared; y equals t plus 8; negative 10 less than or equals t less than or equals 10 (a) Eliminate the parameter to obtain an equation in x and y. (b) Describe the curve and indicate the positive orientation. (a) Eliminate the parameter to obtain an equation in x and y. Choose the correct equation below. A. y equals StartRoot x plus 3 EndRoot B. y equals (x plus 3 )squared C. y equals x squared plus 3 D. y equals 3 plus or minus StartRoot x EndRoot (b) Describe the curve and indicate the positive orientation. A. -15 15 -5 15 x y

  a)  D. y = 3 ±√x

  b)  parabola opening to the right

Step-by-step explanation:

(a) Solving for t in the equation for y:

  y = t+8

  t = y -8 . . . . subtract 8

Substituting into the equation for x, we have ...

  x = ((y -8) +5)^2 = (y -3)^2

Solving for y, we get

  ±√x = y -3 . . . . . take the square root

  y = 3 ±√x

__

(b) The equation describes a parabola that opens to the right.

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.
