From 86 books to 150 books. An increase of 64 books.
(150 - 86) / 86 = 64 / 86 = 0.744 * 100% = 74.40% or 74% increase
150 / 86 = 1.744 * 100% = 174.40%
86 is the basis. It is 100%
If the problem asks for the value of the percentage increase and the rate is given 74.4% of 86. Then 86 * 74.4% = 64. You just add 64 to 86 to get the new total of books which is 150.

1.125
Step-by-step explanation:
A. never
because you are limiting x from 0 to infinite, and all of these are positive.
I not sure but this what i think
Answer: 2
Explanation:
The average rate of change is the net change of the function, i.e. final value less initial value, divided by the interval:
f(b) - f(a) f(1) - (f(-3)
average change rate from a to b = ---------------- = ---------------
b - a 1 - (-3)
f(1) = -(1/2) (1 + 2)² + 5 = -(1/2) (3)² + 5 = 5 - 9/2 = 1/2
f(-3) = -(1/2) ( -3 + 2)² + 5 = -(1/2) (-1)² + 5 = 5 - 1/2 = 9/2
(1/2) - (9/2)
average change rate = -------------------- = 2
1 - 3
That is the answer.
