What are the domain and range of f(x) = 4x – 8?


domain: {x | x is a real number}; range: {y | y > –8}

domain: {x | x is a real number}; range: {y | y > 8}

domain: {x | x > 4}; range: {y | y > –8}

domain: {x | x > –4}; range: {y | y > 8}

Verified Answer :

Answer:

Option A

Step-by-step explanation:

We have given that : \(f(x)=4^x-8\)

To find : domain and range of the function

Solution : The domain of the function is where the function is defined and the given function is defined for all real number

∴ domain: {x | x is a real number}

Now, the range of the function is the set of value that correspond with domain

\(f(x)=4^x-8\)   the range correspond to value when  y > -8

∴ range: {y | y > –8}

Therefore, Option A is correct  

domain: {x | x is a real number}; range: {y | y > –8}
