Question

Which set of parametric equations represents the following function y=square root of x+3

Answer 1

The given equation is:


`y= √(x+3)`

We have to find, which of the given set of parametric equations given in the options, result in the above equation:

The correct answer would be option A.

The equations in option A are:


`x(t) = 5t \\ y(t)= √(5t+3)`

From first equation we can see that 5t is equal to x. Using the value of 5th in second equation, we get the equation as:


`y= √(x+3)`

Therefore, the correct answer is option A
