if f has no absolute max on [0,1] then f is discontinuous (true or false?)
in
Calculus
does that mean that "if f has no absolute max on then f is discontinuous" is true? I know that the extreme value theorem states that if f is...

find values a, b so h(x)= e^(ax) for x≤ 0, = √(x+b) for x>0, is differentiable at x=0
in
Calculus
if the function is continuous e^(ax) =√(x+b) at x=0 e^(0) = √(b) 1 = √(b) 1= b the slope from the left side must equal the slope from the...

in
Calculus
If f has no absolute max on , then f is discontinuous. (true or false?) I think this is false, y=5 has no absolute maximum on the interval and...

in
Calculus
h(x) = e^(ax) for x≤ 0 = √(x+b) for x>0 for which values of a and b will h(x) be differentiable at x= 0 if it is differentiable, d/dx...

finding derivative of an inverse function given f(x) = x^5 +3x +6
in
Calculus
given that f(x) = x^5 +3x +6 is one to one, find (f^-1)' (10) (the derivative of the inverse function at x=10) I know that the derivative of an...
