Answer:
Domain: -∞ < x < +∞
Range : 2 ≤ f(x) < +∞
Step-by-step explanation:
See the graph attached to this question.
The two arrow shows the graph of a function y = f(x).
Now, the value of x varies from +∞ to -∞.
So, the domain of the function is -∞ < x < +∞
Again from the graph the range of the function i.e. values of y varies from 2 to +∞ and including 2.
Therefore, the range of the function is 2 ≤ f(x) < +∞ (Answer)
