Question

The domain of the function f(x)=285x−22 is all real numbers x except for

Answer 1

Given the function:

`f(x)=(28)/(5x-22)`

The domain of the function is all the possible values of x that can be

substituted into the function

The given function is a fractional function

So, the domain is all the real numbers except the zeros of the denominator

So, we will find the zeros of the denominator as follows:

`\begin{gathered} 5x-22=0 \\ 5x=22 \\ x=(22)/(5)=4.4 \end{gathered}`

So, the answer will be:

The domain is all the real numbers x except for 4.4
