Online Square Root Graph Tutors

Online Square Root Graph Tutors Square root function is a function which is expressed under the radical sign . Square root of a function or an expression means that it is raised to an exponent of 1/2. Square root functions can be graphed on an X-Y coordinate plane and we can also find the domain and range of the given function. To graph a square root function, we can plug-in numbers in the place of the variable x and find the function or the y value for those numbers and plot the points on the plane. Example 1: Graph the square root function, y = x. 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 Example 2: Graph the square root function, y = (x 1). Since the function is (x 1), hence the graph of y = x shifts 1 unit to the right. Let x= 1then 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.
