Answer:
i think is Quadratic function
Let +n+ = number of bottles of cranberry juice needed
+2n+ = number of bottles of ginger ale needed
---------------------------
+3.2n+%2B+.9%2A%28+2n+%29+=+20+
+3.2n+%2B+1.8n+=+20+
+32n+%2B+18n+=+200+
+50n+=+200+
+n+=+4+
and
+2n+=+8+
----------------
The most bottles of cranberry juice is 4
4.5 x 4.5 = 20.25 x 4.5 = 91.125 in
Answer: Given relation is a function
A relation is said to be a function if no value in its domain is paired up with more than one value in its range.
Since x values represent the Domain of a relation and y values represent the Range of a relation, in terms of x and y we can say:
A relation is said to be a function if an x-value is not paired up with more than one y-value.
From the above table we can see that all the x values are distinct, so no x value is paired with more than one y-value and thus given relation is a function.
