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.
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. All real numbers are valid inputs.
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. The function values are all real numbers less than 4.
Answer:
Domain: $x\in(-\infty,\infty)$ or $-\infty<x<\infty$ Range: $y < 4$
