What is the range of the function below? y = x A. All real numbers
B. All whole numbers
C. All real numbers less than or equal to 1
D. All real numbers greater than or equal to 1

Option (A)

Step-by-step explanation:

Domain of a function is defined by the x-values (input values) on the graph.

Range of a function is defined by the y-values (output values).

For a function having equation as,

y = x

Since, the given function is defined for all real numbers.

Domain of the function: {x | x ∈ R}

Range of the function: {y | y ∈ R}

Therefore, option (A) will be the answer.
