Answer:
20
Step-by-step explanation:
⇔ We can set up an equation using the information given to us
We can that 16 is equal or the same as, one and two tenths times a number which is 'x' added to negative 8
⇔ The minus cancels out the plus
⇔ Add 8 to both sides to isolate
⇔ Convert to improper fraction to make solving easier
⇔ Multiply both sides by 10 to isolate 12x
240 = 12x
⇔ Divide both sides by 12 to isolate x
20 = x
→ The 'number' is 20

Answer:
Step-by-step explanation:
You have the domain. It is given as -1≤x≤1
Now all you have to do is figure out the range which is the y value. At first glance I think it might be 3, but that does not look very logical. I'll post this much of it now and be back in under an hour with a more complete answer.
Of course! How silly of me. There is a minimum of y = 1 in the range which comes from x = 0
I've included a graph so you can see how this all works.
So the range = 1 ≤ y ≤ 3
