Mean Value Theorem
a. Determine whether the mean value Theorem applies to the following functions on the given interval [a,b]
b. If, so find or approximate the point(s) that are guaranteed to exist by the mean value theorem.
c. Make a sketch of the function and the line that passes through (a,f(a)) and (b,f(b)). Mark the points P (if they exist) at which the slope of the function equals the slope of the secant line. Then sketch the tangent line at P.
1)f(x)=arcsinx; [0,1/2]
Only parts a & b.
solution:
a) yes
b)c=√(1-9/πˆ2)
2)f(x)=x/(x+2); [-1,2]
