Answer : (8,5)
Given
K(x) =
Now we plug in each point and check whether it satisfies our equation
(-64,12)
K(-64) = = 12 so this point lie on graph
(125,3)
K(125) = = 3 so this point lie on graph
(343,1)
K(343) = = 1 so this point lie on graph
(8,5)
K(8) = = 6 so this point does not lie on graph because we got 6 instead of 5
Answer:
0
Step-by-step explanation:
The question lacks the graph to be able to solve it, I was doing a little research and I could find the graph which I will attach:
Already with the figure we can solve the question.
We have that the average exchange rate in this case would only take the normal slope between those 2 lines
. Furthermore we know that the slope (m) is given by:
m = (y2-y1) / (x2 - x1)
From the graph we have to:
y2 = 0
y1 = 0
x2 = 5
x1 = 3
we replace:
m = (0-0) / (5 - 3)
m = 0
Therefore the average rate is 0.
