find the exact value of f''(2) if f(x)= x (3x-4)^1/2

ok cool :) thanks !

thanks !

thanks :)

I'm so confused with inflection and horizontal inflection are they the same thing? what is the best way to see if there is a horizontal inflection. by using the first derivative,with the test of turning points or the second derivative, with the test for concavity?

please help with these questions. show working out please! :) 1. Find the point of intersection of the normals to the parabola x^2 =-12y at the points (4, -1 1/3) and (-2, -1/3) 2. a. Find the equation of the tangent to the parabola x^2 =12y at the point P (6,3). ( the answer is x-y-3=0...

thanks heaps everyone :)

omg, thanks so much SpiralFlex :D

find the length of the diameter of the circle x^2+8x+y^2-12y+3=0 please show all working out!!

find values of A, B and C if 4x^2-3x+7 = (Ax+4)^2 + B(x+4) + C thanks :)

solve 2^(2x-1)-5.2^x +2=0 the dot is multiplication

Find the value of n for which the equation (n+2)x^2 +3x-5=0 has one root triple the other can you please show the working out for the whole question i tried doing it before but it didn't work out thanks

Thanks :)

Find the values of P for which x^2-x+3p-2>0 for all x

Find the value of n for which the equation (n+2)x^2 +3x-5=0 has one root triple the other

find values of m such that mx^2 + 3x-4<0 for all x

find values of m such that mx^2 + 3x-4<0 for all x

btw its find the exact value of f''(2) if f(x) = x times by the square root of (3x-4)

would someone very lovely answer this questions for me and show the working out? find the exact value of f''(2) if f'(x) = x times by the square root of (3x-4) muchly appreciated! please and thankyou :)

yes it's the right answer Shazer2 :) :) and Shadowdude, i will consider that for next time
