Let f(x) = cos(x) + 2x. Where does f have critical points?

adell [148]

Answer:

f has no critical points.

Step-by-step explanation:

We are given:

$f(x)=\cos(x)+2x$

A function has critical points whenever its derivative equals 0 or is undefined.

Differentiate the function:

$f'(x)=-\sin(x)+2$

Since this will never be undefined, solve for its zeros:

$0=-\sin(x)+2$

Hence:

$\displaystyle \sin(x)=2$

Recall that the value of sine is always between -1 and 1.

Thus, no real solutions exist.

Therefore, f has no critical points.

Step-by-step explanation:

3x - 15 = -18

Add 15 to both sides;

3x = -3

Divide both sides by 3;

Enter the ratio as a fraction in lowest terms 2 ft to 10 in.

Rufina [12.5K]

I think it's 2 5\6

because you have 2 whole fts and 10\12 of a foot which reduces to 5/6 when you divide the numerator and denominator by 2 which they have the highest common divider.
