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

1 answer:

8 0

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)

Answer:

$X = $12y

Step-by-step explanation:

In this question, we are asked to give an expression to represent the amount of money charged to a man who stayed in a motel for a particular number of days.

Firstly, we need to know the amount of money charged per day. This is visible from

the question and it is equal to $y.

Secondly, the number of days/night stayed is 12 days. This means that the amount of money he was charged is 12 * y = $12y

Since the amount of money charged is equal to $x, the amount to pay can be expressed in terms of y and x to be

$X = $12y
