Use the function to answer the question.

f(x)=1/4-x
For what value in the domain is the function undefined? Explain your answer.

2 answers

I assume you actually mean
1/(4-x)

this denominator is zero when x = 4 so the function is undefined when x = 4

The way you wrote it means
(1/4) - x which is defined for all real x
Oh sorry about that. Can you explain what undefined means and what domain means?
