The domain of the square root function f (x) = √x is the set of all non-negative real numbers. i.e., the square root function domain is [0, ∞). Note that it includes 0 as well in the domain. In general, the square root of a number can be either positive or negative. i.e., √25 = 5 or -5 as 5 2 = 25 and (-5) 2 = 25.

4 sty 2021 · The sequence of graphs in Figure 2 also help us identify the domain and range of the square root function. In Figure 2 (a), the parabola opens outward indefinitely, both left and right. Consequently, the domain is \(D_{f} = (−\infty, \infty)\), or all real numbers.
The domain and range of the square root function 𝑓 (𝑥) = √ 𝑥 is [0, ∞ [. More generally, the domain of a composite square root function √ 𝑔 (𝑥) can be identified by finding the values of 𝑥 satisfying 𝑔 (𝑥) ≥ 0. The domain and range of the cube root function, 𝑓 (𝑥) = √ 𝑥 , are all real numbers.

The domain of a function includes all real input values that would not cause us to attempt an undefined mathematical operation, such as dividing by zero or taking the square root of a negative number. The domain of a function can be determined by listing the input values of a set of ordered pairs.

Square Root Function. This is the Square Root Function: f (x) = √x. This is its graph: f (x) = √x. Its Domain is the Non-Negative Real Numbers: [0, +∞) Its Range is also the Non-Negative Real Numbers: [0, +∞) As an Exponent. The Square Root Function can also be written as an exponent: f (x) = x½. Plot the graph here. Square Root Algebra Index.
