Question

What are the domain and range of the function?

A.) {X|X is a real number
B.) {X|X > 43/ 1yz 0
C.) {X|X is a real number; y|y > 4
D.)X > 4; y|y > 4

Answer 1

domain is the numbers you can use
range is the numbers you get from inputing the domain


domain is just all real numbers except the ones that make undefined things like divisions by 0 or square roots of negatives

we are given
f(x)=4(∛81)x
which simplifies to
f(x)=4(3)x or
f(x)=12x

the domain is all real numbers
range is all real numbers

not sure what your options mean tho

Answer 2

Both the domain and range are all real numbers
