Answer:
$21
Step-by-step explanation:
2Lbs. = $6
(2/2) = (6/2)
1Lbs. = $3
(1*7) = (3*7)
7Lbs = $21
Since strawberries are priced on weight, you first need to find the weight of one pound. The prices need to be proportional, so whatever you do to one side of the equal sign, you need to do to the other. Divide both numbers by 2. One pound costs three dollars. Then multiply both numbers by 7. Seven pounds of strawberries cost twenty-one dollars

Answer:
Domain is all real Numbers
Range is all numbers over 0 - (0,
∞
)
Explanation:
One thing that you have to remember is that when you are finding the domain of a polynomial, it is all real number. it runs from
(
−
∞
,
∞
)
For finding the range, in a quadratic formula, you have to find when the finction has it's vertex. That is the place that the max or min happens and then you can find the range from there.
in this situaltion we found that the vertex is at the the origin at (0,0)
therefore the range is (0,
∞
)
