Answer:
(a) Range: y > 2
(b) Domain: All reals
Explanation:
Range
The range of a function is the set of all possible output values (y-values).
A horizontal asymptote is a horizontal line that the curve gets infinitely close to, but never touches. It is displayed as a horizontal dashed line. Therefore, the horizontal asymptote of the graphed exponential function is y = 2.
Since there is a horizontal asymptote at y = 2, and the curve appears to be always above this line, it indicates that the range of the function is all y-values greater than 2.
Domain
The domain of a function is the set of all possible input values (x-values).
As the x-values of graphed exponential function appear to be unrestricted, the domain of the function is all real numbers.
