Graph and find the domain and range of the function

Question

f(x)=(1/4)x-1

 

My class is in the functions section now but i can't figure out how to solve this problem. I've tried using multiple examples of the functions we've gone over but none seem to work especially when it comes to finding the doman and range which they also ask for in the problem.  please help me with this. And please show how  you did it so i can understand and do other problems like this in the future.

Answer 1

Because of the limitations of the WyzAnt platform, you cannot type a rational algebraic function because you can only type one line.  If the denominator is the expression (4x-1), you MUST use parentheses.

 

In this case, the denominator cannot be allowed to be zero. Therefore x can be any Real number EXCEPT ¼
