WebWe could say that the domain is a "variable" part of a function, just as its definition, so for example f (x) = sin x ( (0 < x < pi / 2)) g (x) = sin x ( (x belonging to Complex numbers)) are completely different functions, as their domains are different.

So we know that y will be greater than or equal to 0. So, the range of the square root function is y ≥ 0. Let us understand by taking an example. y = √ (x + 4) [ random example assumed ] According to the definition of square root function, x + 4 must ...
WebJan 31, 2024 · Practice finding the domain of a square root function with practice problems and explanations. To find the domain of this type of function, set the bottom equal to zero and exclude the x value you find when you solve the equation. The radicand (the expression under the radical) must be positive or equal to 0 so that f ( x) takes real. ... WebFeb 20, 2024 · Find the domain of function f defined by f(x) = √(x - 1) Solution to Example 1. For f(x) to have real values, the radicand (expression under the radical) of the square root function must be positive or equal to 0. Hence x - 1 ≥ 0 The solution set to the …
