Answer 1

Answer:

13

Step-by-step explanation:

this is the right answer

Answer 2

Answer:

f'(1)=f'(2)

Step-by-step explanation:

f(x) = 2x³-9x²+12x+9

f'(x)=6x²-18x+12

f'(1)= 6(1)²-18(1)+12

=6(1)-18+12

=6+12-18

=0

f'(2)= 6(2)²-18(2)+12

=6(4)-18(2)+12

=24-36+12

=24+12-36

=0

ans. f'(1)=f'(2)
