The question is
If f(x) = 7x^3 + 8x^2 - x + 11, evaluate :
a, Integral +1 - -1 f(x) dx
b, Integral +1 - -1 f'(x) dx
c, Integral +1 - -1 f''(x) dx
For a, Just integrate each individual and then input the figures which gave me
1.75x^4 + (8x^3)/3 - 0.5x^2 + 11x
Which when I input the figures gives me 27 1/3.
It is b, which I am unsure about. Do I intergrate 1.75x^4 + (8x^3)/3 - 0.5x^2 + 11x and then put the values in?
Some guidence would be most appreciated, thank you.
