The right side of the x-axis represents positive domain and the left side of the x-axis represents a negative domain.
So a radical function with an even index could have a domain of x≥0, so that's why they only appear on the right side.
Whereas a radical function with an odd index has a domain of all real numbers, so they appear on both sides.
The easiest scenario to see why this is true is to test square root and cube root.
You can't have a square root (even index) of a negative number, but you can have a cube root (odd index) of a negative number.

Values of x and y will be 12 and 5 respectively.
It's given in the question,
- Three points Q, R and S are collinear.
- Coordinates of Q → (2, 0)
- Coordinates of R → (8, 3)
- Coordinates of S → (x, y)
- QR : RS = 3 : 2
Since, expression for the coordinates of a point (h, k) which divides the segment joining points and
in the ratio of m : n is given by,
h =
k =
Since, R is a point on segment QS dividing in the ratio of 3 : 2, coordinates of R will be,
Similarly,
Therefore, values of x and y will be 12 and 5 respectively.
