Therefore the square root function 4 given by f x sqrt x is not defined to be a real number if the x values are negative The smallest value in the domain is zero The smallest value in the domain is zero Square roots only have two factors Cube roots have three For example the square root of 64 is 8 because 8X8 64 The cube root of 64 would be 4 because 4X4X4 64 Another example of cube roots could be 27 The Cube root of 27 can be expressed as 3X3X3 Therefore the cube root of 27 is 3 Got it
The square root function f x sqrt x text is a function that returns the principal positive squart root of the input Here are the details Domain All nonnegative real numbers the square roots of negative numbers are not real numbers Range All nonegative numbers Graph Its graph is The graph of the square root function is the Using the fact that sqrt x sqrt y 2 x y 2 sqrt xy find the square root of 5 sqrt 24 This number can be expressed in the form sqrt a sqrt b where a leq b Find the value of b a
