Answer:
Range = 1 ≤ y ≤ 5
Step-by-step explanation:
The range of the graph is all possible y-values that is plotted in the graph.
The range includes y-values include y = 1, and y-values that fall between y = 1 and y = 5, 5 inclusive.
Range = 1 ≤ y ≤ 5
Again, a function is where for every x, there is only one value of y. If you look, for x of -2, there is y of 1 and -3. So removing one of them would work. The only one answer that works in (-2, 1)

Answer:
5%
Step-by-step explanation:
<u>price after discount :</u>
9 600 - 9 600×40%
= 5760
<u>Original price (price without profit) :</u>
let x be the original price of the device.
x + x × 20% = 5760
Then
x = (5 760×100)÷120
= 4 800
<u>Original price increased by 30% :</u>
4 800 + 4 800×30%
= 6 240
<u>the discount needed to increase the profit by 10% :</u>
[(9 600-6 240)÷9 600]×100
= 35%
Then
to increase the profit by 10% ,we have to reduce
the percent of discount to :
40% - 35%
= 5%
