Can you please help me with this exerciseI am sorry for the mess I hope it makes sense

5. The sum of the smallest and largest value of the function x3 -3x2 +1 in the interval (-1; 4] is: 1. The values of the local extremes of the A) 3 B) 17 function 4x8-15x218%+7 are: B) -2 D) 14 Hyunwa (4x' -15x2 -18x + 1out A) 11- H-35 6) --H3 Part II B) 11- H-74 T) 2 H -74 6. Find the smallest value of the function 3 2. The function f(x) = x(2Vx-9) (x) = ~x-10x' -12x2 +120x-7 there is a local extreme in the point (xo, f(x). The congregation in the interval [-3; 2]. xo + f(x is equal to: A) -18 B) -9 7. Find the smallest and largest value of the B) -8 D) -3 function f(x) - in X +2 *275 the interval (-00; +0) 3. The smallest value of the function 2x3 -3x2 -36x+5 , in the interval [-3; 11] is: Part I A) -27 B) -15 B) -76 D)-67 8. Find the values of the parameter a for which - the function 4. The biggest value of the function x* -4x +7 in the interval [-2; 3) is: f (x) = ax' -2x3 +5x+9 A) 4 B) 76 has a local minimum at the point where B) 27 D) 35 the function f(x) =5x3+6x2 -3x+1 has a local maximum
