the graph of an exponential function is shown in the figure below. the horizontal asymptote is shown as a dashed line. find the range and the domain. write your answers as inequalities, using x or y as appropriate. or, you may instead click on \empty set\ or \all reals\ as the answer. (a) range: (b) domain:

the graph of an exponential function is shown in the figure below. the horizontal asymptote is shown as a dashed line. find the range and the domain. write your answers as inequalities, using x or y as appropriate. or, you may instead click on \empty set\ or \all reals\ as the answer. (a) range: (b) domain:

Answer

Explanation:

Step1: Recall domain - definition

The domain of a function is the set of all possible input values (x - values). For an exponential function, there are no restrictions on the x - values.

Step2: Recall range - definition

The range of a function is the set of all possible output values (y - values). Looking at the graph, the horizontal asymptote is at y = - 4 and the function approaches this value from above. So the y - values are greater than - 4.

Answer:

(a) range: $y > - 4$ (b) domain: All reals
