Answer:
Step-by-step explanation:
2)
x^3 - 3x^2 -24x +7
Find the derivative of this: which is,
3x^2 - 6x -24
in order to find the minimum you must set it up equal to 0
0 = 3x^2 - 6x -24
0 = 3(x^2 -2x -8)
0 = (x-4)(x+2)
x= 4
x=-2
Ignore the negative 2 answer, because it is unrealistic!
Hence, velocity is: 4 cm/sec
3) and 8) aren't visible, hence, i can't answer them
9) a. (-1,1/2) is where the f is both decreasing and concave down as shown in the graph down below.
Hope this helps!
