Respuesta :

the end of behavior of a function is the behavior of the graph of the function

Answer:

Step-by-step explanation:

Recognize that this is the exponential function y = e^x with some tweaks:

f(x) = 2e^x + 1, as compared to y = e^x.

y = e^x is a basic function that we all should know well.  Its graph looks much like the graph shown as "Part A."  The graph starts in Quadrant II, crosses the y-axis into Quadrant I, and then continues growing rapidly as x increases.

As x => positive infinity, y => positive infinity.  This is true of f(x) = 2e^x + 1 also.

As x => negative infinity, y => 0 (speaking of y = e^x).

As x => positive infinity, f(x) = 2e^x + 1 => positive infinity, in Quadrant I.
