Question

what are the domain and range of the function f(x) = 4(3 square root 81)^x?x; y > 0 x > 4; yx; yx; y > 4

Answer 1

Answer: x; y>0

Explanation:

Answer 2

we are given

`f(x)=4(3√(81) )^x`

Domain:

we know that domain is all possible values of x for which any function is defined

Here , since, x is only exponent

so, we can take any values of x

it will be defined for all values of x

so, domain is all real numbers

x

Range:

we know that

range is all possible values of f(x) or y

Since, there is no negative sign here

so, f(x) will always be positive and greater than 0

so, range is y>0
