Question

Identify the local maximum value for the function f (x) = x^6 - 6x^4 + 5, using the first derivative test.

Answer 1

x = 2,-2

Answer 2

also x=0

Answer 3

Is this some kind of a joke?

Answer 4

Why so???

Answer 5

You tell me meanie :p You're giving me wrong answers on purpose
-_-

Answer 6

Evalute f'(x) = 0 and equate the equation.
f(x) =x^6 - 6x^4 + 5
f'(x)=6x^5-24x^3 = 0 find the value of x .This will give you local maximum value

Answer 7

i.e 6x^3(x^2 - 4) =0 find the possible value of x?

Answer 8

the value of x from the equation will be x = 0,-2,+2.

Am I correct?Otherwise you please explain it?

Answer 9

Lol. The possible answers for this multiple choice question are 2, -2,4, or 0. Thats the reason I said that :/ Dont be mad at me :(
