Question

What is the range if the function y=4e^x

Answer 1

Answer:

the range of function $4e^{x}$ is (0, ∞)

Step-by-step explanation:

Function range definition:-

The set of values of the dependent variable for which a function is defined

we need to find the range of function $4e^{x}$

The range of an exponential function of the form $n^{ax+b}+k$ is $f(x)>k$

$k=0$

As x grows without bound, $e^{x}$ increases without bound.

Thus, the range is (0, ∞).

Answer 2

Answer:

(0, ∞)

Step-by-step explanation:

As x becomes increasingly negative, e^x decreases towards zero (but never touches zero).  As x grows without bound, e^x increases without bound.

Thus, the range is (0, ∞).
