Answer:
34
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ 1, 6 ]
f(b) = f(6) = 6³ - 9(6) = 216 - 54 = 162
f(a) = f(1) = 1³ - 9(1) = 1 - 9 = - 8, thus
average rate of change = =
= 34
Answer:
He have <u>17 CDs</u> on Monday.
Step-by-step explanation:
Given:
On Tuesday James bought seven CDs. On Wednesday half of all the CDs that he had were destroyed. On Thursday he had 12 left.
Now, to find the CDs he have on Monday.
Let the CDs he have on Monday be
<em>So, on Tuesday as James bought 7 CDs:</em>
<em>Now, on Wednesday half of all the CDs that he had were destroyed:</em>
As, given on Thursday he had left CDs = 12.
According to question:
<em>Multiplying both sides by 2 we get:</em>
<em>Subtracting both sides by 7 we get:</em>
Therefore, he have 17 CDs on Monday.
Answer:
Domain = {3,4,9}
Range = {2, 6, 8, 9.5}
Given relation is NOT a function.
Step-by-step explanation:
Given relation is relation is ((9,6), (3,8),(4,9.5), (9,2)}.
Now we need to determine if given relation is a function or not.
We also need to find the domain and range.
((9,6), (3,8),(4,9.5), (9,2)}
Domain is basically the collection of x-values
So Domain = {3,4,9}
Range is basically the collection of y-values
So Range = {2, 6, 8, 9.5}
Since given relation contains repeated x-value "9".
So the given relation is NOT a function.
