Q. What is the domain of this function? y=xChoices: {x∣x≥0}{x∣x≤0}{x∣x<0}{x∣x>0}
Identify the variable: Identify the variable that represents the domain. In a function y=f(x), the domain consists of all possible values of x for which the function is defined.
Determine values of x: Determine the values of x for which the square root function is defined. The square root function y=x is defined only for non-negative numbers, meaning x must be greater than or equal to 0.
Choose correct domain: Choose the correct domain from the given choices. Since the square root function is defined for non-negative numbers, the domain of y=x is all x values that are greater than or equal to 0. Domain: {x∣x≥0}
