I'll post what I have already solved, but I'm not sure if there's more to the question.

f(0) = (0)^3 = 0 f(1) = (1)^3 = 1 \[\frac{ 1-0 }{ 1-0 }=\frac{1}{1}=1\] The derivative of the function is 3x^2 3x^2 = 1 x^2= 1/3 x = sqrt(1/3) or -sqrt(1/3) Since only sqrt(1/3) is found in [0,1], then it is the only answer.

Is there anything else this question is asking me to do? (It's just worded confusingly to me)

do you have to define how the mean value thrm applies to it? i think it has to do with being continuous along the interval
amistre64
  • amistre64
other than that, you did well at finding x=c that has a slope equal to the slope between x=a and x=b

What do mean by define how it applies?
amistre64
  • amistre64
what are the required conditions for the MVT to be applicable?
anonymous
  • anonymous
The function must be continuous and differentiable
amistre64
  • amistre64
..." if f(x) is defined and continuous on the interval [a,b] and differentiable on (a,b)" ... http://www.sosmath.com/calculus/diff/der11/der11.html correct, and since this function is defined, continuous, and diffy-able then yada yada
amistre64
  • amistre64
one of the common examples of a fail for this is f(x) = 1/x, on the interval (-1,1)
amistre64
  • amistre64
a slope can be defined across the interval, but the function has no value in the interval that matches that slope ... it is not continuous or diffy-able at x=0 within the interval

Ah okay. Could you interpret this by chance? ... "Find any tangent lines to the graph of f that are parallel to the secant line."
anonymous
  • anonymous
I could post the problem if it would help
amistre64
  • amistre64
more info usually helps, but the idea is to find the slope ofthe secant line in order to evaluate the derivative tha tmatches it
anonymous
  • anonymous
Is there a formula to finding the slope of the secant line?
anonymous
  • anonymous
Oh nevermind! It's 2/3. I've already solved for it.
amistre64
  • amistre64
:) f(b)-f(a) ------- b-a
anonymous
  • anonymous
So how would I find the parallel lines?
amistre64
  • amistre64
parallel lines have the same slope ....
anonymous
  • anonymous
So it would be any function with the slope 2/3?
amistre64
  • amistre64
the derivative of the function (if one is given) define the slope at any single point
amistre64
  • amistre64
any value x=c of which f'(c) = 2/3
amistre64
  • amistre64
this is just another wording of the MVT

Okay thank you!
