Domain:
We know that
domain is all possible values of x at which y is defined
so, all given x-values in this table is domain
so, domain is {-2, -1, 0, 1, 2, 3}...........Answer
Range:
We know that
range is all possible values of y at which x is defined
so, all given y-values in this table is range
so, range is {-3, -1, 1, 3,5, 7}...........Answer
Answer:
with proportional relationships, you can simply divide the y coordinate by the x coordinate to find the unit rate: In this case, if (5,4) lies on the line then you have 5 lbs of potatoes for 4 dollars or .80 cents for 1lb of potatoes. The point (10,8) represents 10 lbs of potatoes for 8 dollars. Here you can see that dividing 8 by 10 we once again get the unit rate of .80 cents per 1 lb of potatoes.
x = lbs of potatoes and y = price(4,3)....this means 4 lbs of potatoes cost $ 33/4 = 0.75 cents per lb <== 1 lb of potatoes cost 0.75(8,6)...this means that 8 lbs of potatoes cost $ 6
Hope this helps

Answer: (13, 47)
The expression t = 4 means that 4 units of time have come off the clock (possibly 4 seconds). Plug this value into each equation given for x and y
x = 2*t + 5 = 2*4 + 5 = 8 + 5 = 13
y = 3*t^2 - 1 = 3*4^2 - 1 = 3*16 - 1 = 48 - 1 = 47
In short, if t = 4 then it leads to x = 13 and y = 47 at the same time. These x and y values pair up to get the final answer (13,47)
