Sagot :

The given function is expressed as

f(x) = 2^(x + 1)

The domain of a function is the set of all the possible values of x that would satisfy the function.

The range of a function is the set of all the possible values of y that would satisfy the function.

Since the fuction has no denominator or even root, the values of can be all real numbers. This means that the domain would be between - infinity and infinity

For the range, no matter how small the value of x that we input into the function, the value of f(x) or y would never be lesser than zero. Also, there is no limit to the value of f(x) even if we input very large values of x. Thus, the range is between 0 and infinity. Thus,

the correct option is the second one
