Consider the function f(x) = V5x – 5+1
Which inequality is used to find the domain?

The domain is  Df(x)∈[1,∞[

Explanation:

f(x)=√5x−5+1

To find the domain, we look what's under the square root sign.

5x−5≥0

5x≥5

x≥1

Therefore the domain of f(x) is

Df(x)∈[1,∞[

answer: which of the following can speed up the rate at which the liver breaks  

down alcohol?

question 1 options:

carbohydrates  

coffee  

nothing  

high-protein meals  

step-by-step explanation:

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
