A graph can increase or decrease at an interval or several intervals
- The interval with the longest curve or line represents the greatest change.
- The intervals with the greatest rate of change are ab and de
- The intervals with the least rate of change are bc and cd
- The intervals with the equal rates of change are ab and de
<u>Part A: How to determine the longest interval</u>
The longest interval will have a great change in the y-values, and a small change in the x-values.
An instance of such interval is interval ab
<u>Part B: Intervals with the greatest rate</u>
Intervals ab and de have equal rates, and they cover the same vertical and horizontal distances, as described in (a) above.
Hence, intervals ab and de have the greatest rate of change
<u>Part C: Intervals with the least rate</u>
Intervals bc and cd have equal rates, and they cover the same vertical and horizontal distances,
Hence, intervals ab and de have the least rate of change
<u>Part D: Intervals with the equal rate</u>
As said in (b) and (c),
- Intervals ab and de have equal rates
- Intervals bc and cd have equal rates

Answer:
Step-by-step explanation:
A
(2x - 5)(x + 1)
B)
The x intrcepts occur when the factors equal zero.
2x - 5 = 0
2x = 5
x = 5/2
x = 2 1/2
C
I will give the the minimum from completing the square
y = 2(x - 0.75)^2 - 6.125
as x approaches + infinity, y approaches + infinity.
as x approaches - infinity, y approaches + infinity.
It's a quadratic. The y values go to plus infinity, when x goes from - infinity to + infinity.
D
Desmos is the most useful tool for this part of the question. What it shows is the two roots and the minimum at (0.75,-6.125. A parabola does what the end behavior describes. The roots are clearly labeled as is the minimum.
