If the function f has a continuous derivative on [0,c], the the integral(o to
c. of f'(x)dx=
a.f(
c.-f(0)
b.absolute value (f(
c.- f(0))
c. f(
c.
d.f'(x)=c
e.f"(
c.-f"(0) My work: so the the answer to the integral is f(x) and when find the answer from o t0 c, it is f(
c.-f(0).
is that the right answer? i'm confused because is there anything i have to do with the point [0,
c. or is that unneccessary info.
problem #2: let f be a polynomial function with degree greater than 2. if a does not equal b and f(
a.=f(
b.=1, which of the following must be true for atleast one value of x between a and b?
I)f(x)=0 II)f'(x)=0 III)f"(x)=0 you can choose more than one choice in the choices mentioned of I, II, III
i'm having trouble coming up with the equation and choosing a and b
The correct answer to (#1) is f(
c.-f(0). That is because the definite integral of a function (
f. is the difference between the indefinite integral (
f. evaluated at the two limits of integration.
The correct answer to (#2) is f'(x) = 0. Imagine all possible continuous curves you can draw from a to b, going though f = 1 at both points. The curve MUST have zero slope somewhere. There is no requirement that f or f'' be zero at intermediate points. you don't need an equation to prove this. You just need to invoke the Mean Value Theorem
