A curve sketch |
2007-11-22 |
 |
From Ahson: Find critical points, determine the monotonicity and concavity and sketch
a graph of f(x) with any local maximum, local minimum and inflection
points labeled:
1. f(x) = x^4 - x^3 - 3x^2 + 1 Answered by Harley Weston. |

Increasing and decreasing for functions |
2007-11-09 |
 |
From David: Direction: Identify the open intervals on which the function is increasing or decreasing.
f(x)=1/(x^2)
f'(x)= -2/(x^3)
i understand how to get up until there, and the undf. is x=0, but now i'm having problem setting up the number table chart. i cant remember how, and where to place the increase and decrease + - the
chart, for example <---------0----------> where would the increase and the decrease be place? Answered by Harley Weston. |

f(x) = (x^4) - 4x^3 |
2007-07-22 |

From Michael: I'm a student who needs your help. I hope you'll be able to answer my question.
Here it is: Given the function f(x)=(x^4)-4x^3, determine the intervals over which the function is increasing, decreasing or constant. Find all zeros of f(x) and indicate any relative minimum and maximum values of the function.
Any help would be appreciated. Thank you for your time. Answered by Harley Weston. |
