Question

Find any relative extrema of the function. (Round your answers to three decimal places.)
f(x) = arcsec(x) − 6x

Answer 1

find f'(x) and then where it's 0 or undefined

Answer 2

I guess it's like the other one, find the derivative and then solve for x/y?

Answer 3

Yup, and you can use a calculator to differentiate.

Answer 4

and evaluate.

Answer 5

\[\frac{1}{|x| \sqrt{x^2-1}}\] -6?

Answer 6

I believe so.

Answer 7

yup, so one of your values would've been:
x=0, x=1, and then just set that fancy looking fraction equal to 6 and solve for x.

Answer 8

Sorry, I'm lazy ;)

Answer 9

np

Answer 10

so now we need to find the y's right? since the min is 0 and the max is 1?

Answer 11

Wait min is not 0 and max is not 1, I mean you may be right but you have to test them first.

Answer 12

oh sorries :P.

Answer 13

Keep in mind, max and min aren't measured by how big x, they're measured by how big y is.

Answer 14
