Answer:
Option A
Step-by-step explanation:
We have given that : [tex]f(x)=4^x-8[/tex]
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
[tex]f(x)=4^x-8[/tex] 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}
