consider the function f(x)= x^3+6x^2+9x+4
-state the intervals over which f(x)>0 and f(x)<0
&&
- show that there is a local maximum at x=3 and state the coordinate.
same with
f(x)= -3x^4-2x^3+15x^2-12x+2
-state the intervals over which f(x)>0 and f(x)<0
&&
- test the values x=0.5 and x=-2 to determine id they are local minimums and/or maximums and state the coordinates.
THANKSSS!
