Answer: Domain: 0,1,2,3 and 4 and Range: 1,2,4,8 and 4
Step-by-step explanation:
The domain is the set of all inputs that makes the function definable. As we see the function looks like an exponential function which means the domain is all real numbers.
So the inputs are 0,1,2,3 and 4
the outputs are 1,2,4,8 and 4
