The function, f(x) = √x is also called as the parent function since other square root functions are derived from it.

Let x = 0, then y = √0= 0. Coordinate point is (0, 0)

Let x= 1, then y= √1 = 1. Coordinate point is (1, 1)

Let x= 2, then y= √2= 1.41. Coordinate point is (2, 1.41)

Let x = 3, then y= √3= 1.73. Coordinate point is (3, 1.73)

The graph looks as shown when the above points are plotted

Since the function is (x – 1), hence the graph of y = √x shifts 1 unit to the right.

Let x= 1 then y= √(1- 1)= 0.Coordinate point is (1, 0)

Let x= 2, then y= √(2- 1) = 1. Coordinate point is (2, 1)

Let x= 3, then y= √(3- 1)= 1.41. Coordinate point is (3, 1.41)

Let x= 4, then y= √(4- 1)= 1.73. Coordinate point is (4, 1.73)

The graph looks as shown when the above points are plotted.
