Answer:
(a) rate of change = 8
(b) Function: y = 8x
(c) Domain: 0 ≤ x ≤ 2
Range: 0 ≤ y ≤ 16
Explanation:
Looks like a inverse variation sequence.
Inverse Variation formula: y = k(x)
Take two points: (1, 8), (2, 16)
Find the value of k which is constant also considered as <u>rate of change</u>.
<u>Insert values</u>:
===========
Equation: y = 8x
Domain lies in the x axis, Range lies in the y axis.
Answer: C. is the right answer.
Step-by-step explanation:
Given: The cost of a chessboard at Odyssey Gifts is $6.
The function F(x) = 6x gives the cost of x chessboards.
Since x is the number of chessboards, thus the domain of the function should be the set of whole numbers.
Therefore, Domain= {0,1,2,3,4,5,....................}
when we put the values for x from the domain in the function we get values multiples to 6.
therefore range of the function={0,6,12,18,24,30,......}
Hence, C is the right option.
