Which set of parametric equations represents the following function? y=/x+3?
(everything in parenthesis is under a square root)
A.) x(t)=5t , y(t)=(5t+3)
B.) x(t)=5t, y(t)=(1/5t+3)
C.) x(t)=1/5t, y(t)=/5t+3
D.) x(t)=1/5t, y(t)=(1/5t+3/5)

Respuesta :

The given equation is:

[tex]y= \sqrt{x+3} [/tex]

We need to find which set of parametric equations, result in the equation given above. The correct answer is option A.

[tex]x=5t, y= \sqrt{5t+3} [/tex]

From first equation, we can write t =x/5. Using this value in second equation, we get:

[tex]y= \sqrt{5( \frac{x}{5} )+3} \\ \\ y= \sqrt{x+3} [/tex]

Thus the set of equations in option A result in the given relation.
So, the answer to this question is option A
