Find the maximum and minimum value of the function on the given interval, if:
y=5x^3-15x+5, x ∈[-4;0].
Answer:
1) Enter the required elements of y', starting with the highest degree of variable x (enter the answer as 4 x^2 +5x-2):
y'=
2) Enter zeros of the derivative (first, specify the smallest number):
x1= belong to the segment [-4;0]
x2= belong to the segment [-4;0]
3) Calculate the value of the function at the ends of the given segment and at the critical point and specify the maximum and minimum value of the given function :
y(-1)= max
y(the critical point)= max
y(6)= min
