Answer:
- 6
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
here [ a, b ] = [ - 7, - 1 ]
f(b) = f(- 1) = (- 1)² + 2(- 1) - 8 = 1 - 2 - 8 = - 9
f(a) = f(- 7) = (- 7)² + 2(- 7) - 8 = 49 - 14 - 8 = 27
Hence
average rate of change = 
= 
= - 6
Bob brought 3 autographed baseball for show and tell.Now, that 3 autographed is said to be 1/6 of his whole collection.Let's find out how many autographed did Bob have in total.=> 3 autographed = 1/6 of his collections.To be able to have a value of 1 whole collections we need 6 1/6s=> 1/6 + 1/6 + 1/6 + 1/6 + 1/6 + 1/6 = 6/6 or 1Thus, the value of his current autographed in hand will be multiplied with 6=> 3 * 6 = 18<span>Therefore, he have a total of 18 autographed.</span>
The answer is true, and let me explain this to you like this:
<span>F(x) = 4x - 6
when x = 1, F(x) = 4 * 1 - 6 = -2
when x = 2, F(x) = 4 * 2 - 6 = 2
when x = 3, F(x) = 4 * 3 - 6 = 6
when x = 4, F(x) = 4 * 4 - 6 = 10
</span><span>second row is: -2, 2, 6, 10
</span><span>differences are: 2 - (-2) = 4; 6 - 2 = 4; 10 - 6 = 4
</span>So, the <span>second row is in arithmetic progression.
Hope this is what you were looking for</span>
