Given f (x) = 4x-1, what is the domain value if the range is - 5?

So domain is what numbers you can put in so for functions lets say f (x) = x+1 if you put in 3 for x then you would have f (3) = 3+1 so just put in the values they give you and the function will give you something else so

f (x) = 4x-1

f (-5) = 4 (-5) - 1

f (-5) = - 20-1

f (-5) = - 21

the domain is (-5) and the range is (-21)
