QuestionFind the domain of the function f(x)=7xf(x) = 7x.

Studdy Solution

STEP 1

Assumptions1. The function is f(x)=7xf(x)=7x . We are looking for the domain of this function. The domain of a function is the set of all possible input values (often the "x" variable), which produce a valid output from a particular function.

STEP 2

The function f(x)=7xf(x)=7x is a linear function, which means it's a straight line when graphed.

STEP 3

For a linear function, the domain is all real numbers, because you can put any real number into the function and get a valid output.

STEP 4

Therefore, the domain of the function f(x)=7xf(x)=7x is all real numbers, which can be written in interval notation as (,)(-∞, ∞).
The domain of the function f(x)=7xf(x)=7x is (,)(-∞, ∞).
