the graph of an exponential function is shown in the figure below. the horizontal asymptote is shown as a dashed line. find the domain and the range. 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) domain: (b) range:

the graph of an exponential function is shown in the figure below. the horizontal asymptote is shown as a dashed line. find the domain and the range. 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) domain: (b) range:

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 = 0 and the function values are above this asymptote.

Answer:

(a) All real numbers, which can be written as $x\in(-\infty,\infty)$ or $-\infty<x<\infty$ (b) $y > 0$
