Answer:
Option A
Step-by-step explanation:
Domain of a function is a set of x-values (input values).
Range of a function is a set of y-values (output values).
Since, input and output values of the function given in the graph vary from negative infinity to positive infinity
Domain of the function given in the graph will be,
(-∞, ∞)
And range of the function is,
(-∞, ∞)
Option (A) will be the correct option.
