Answer:
Step-by-step explanation:
We have to choose the function from the given options which have a range (-∞, a] and a domain [b,∞) where a < 0 and b < 0.
I think the function is ......... (1)
Here, x - b must be greater than equal to zero for the function to be real.
Hence, x - b ≥ 0
⇒ x ≥ b
So, the domain is [b, ∞).
Now, putting x = b in the equation (1),we get f(x) = a and putting x = ∞, we get f(x) = - ∞.
Therefore, the range of the function is (-∞, a]. (Answer)

Answer:
Step-by-step explanation:
I am very sorry if this doesnt make sense but i tried to give you an example for the first one so you could figure out the 4 and 5.
If y=12 when x=6, determine y when x=18.
Ok if y=12 and x=6 they add up to 18. So X=6 then you are going to have to times 6 by three to get x to equal 18. That means we have to times y by 3 also which equals 36. We can check this by making sure they are congruent or the same. So if the origanal question said y equals 12 and x equals 6. How do you make sure it's the right answer? What do they have in commmon? Well to get 12 you have to multiply 6 by 2 to get 12. And to get 6 you have to divide 12 by 2. So the common number is 2. So for x to equal 18 we have to figure out is the have something in common, so 18 times 3 equals 36 and if 36 divided by 3 we get 18. So the common number is 3.
