What is the range of the function y=4e^x?
all real numbers greater than 0
all real numbers less than 0

The range of the exponential function y=4e^x is all real numbers greater than 0 (first option)

Solution: The range of a function is the values of the dependent variable "y". In the case of a exponential function of the form y=a^x, you will get for "y" numbers greater than 0:

y=e^x → Range is all real numbers greater than 0

and if you multiply by 4:

y=4e^x, you will obtain numbers greater than 0, then:

Range of the function y=4e^x is all the real numbers greater than 0.

All real numbers greater than 0

Step-by-step explanation:

We have been given the function

Range is the set of y values for which the function is defined.

Now, solve the equation for x and then see which real values of y we can take.

Divide both sides by 4

Take natural log both sides

logarithmic function is defined for positive values only.

Thus, we have

Hence, range is all real numbers greater than 0

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
