Use long division.
y - 1
-------------------------------
y³+1 | y⁴ - y³ + 2y² + y - 1
y⁴ + y
-------------------------------
- y³ + 2y² - 1
- y³ - 1
---------------------------
2y²
Answer: y - 1 + 2y2 ÷ y³+1
Note:
The correct answer should be written with parenthesis, as y - 1 + y²/(y³+1) in order to avoid ambiguity.
If the sample is truly random, every member of the population should have an equal chance to be selected. Because of this, Paula and Peter's probability of being chosen will be equal: 1/9800
the graph of the parabola is above the x-axis, so the derivative is always positive and therefore the initial function is increasing in its whole domain.
The function is decreasing when its first derivative is negative. The first derivative of this function is negative for
so for
the function is decreasing.
The function is increasing when its first derivative is positive. The first derivative of this function is always negative therefore this function is never increasing.
