If f '(3) = 0 and f"(3) < 0, then which of the following must be true?

There is an inflection point at x = 3

There is an x-intercept at x = 3

d d x ( cos ⁡ x ) = \frac{d}{dx}\left(\cos x\right)= d x d ( cos x ) =

− sin ⁡ x -\sin x − sin x

− sec ⁡ x -\sec x − sec x

d d x ( x − 3 sin ⁡ x ) = \frac{d}{dx}\left(x-3\sin x\right)= d x d ( x − 3 sin x ) =

1 − 3 cos ⁡ x 1-3\cos x 1 − 3 cos x

1 + 3 cos ⁡ x 1+3\cos x 1 + 3 cos x

1 − 3 sin ⁡ x 1-3\sin x 1 − 3 sin x

1 + 3 sin ⁡ x 1+3\sin x 1 + 3 sin x

d d x ( x sin ⁡ x ) = \frac{d}{dx}\left(x\sin x\right)= d x d ( x sin x ) =

x cos ⁡ x + sin ⁡ x x\cos x+\sin x x cos x + sin x

x sin ⁡ x + cos ⁡ x x\sin x+\cos x x sin x + cos x

x sin ⁡ x − cos ⁡ x x\sin x-\cos x x sin x − cos x

d d x ( sin ⁡ x + cos ⁡ x ) = \frac{d}{dx}\left(\sin x+\cos x\right)= d x d ( sin x + cos x ) =

− sin ⁡ x + cos ⁡ x -\sin x+\cos x − sin x + cos x

sin ⁡ x + cos ⁡ x \sin x+\cos x sin x + cos x

sin ⁡ x − cos ⁡ x \sin x-\cos x sin x − cos x

− sin ⁡ x − cos ⁡ x -\sin x-\cos x − sin x − cos x

d d t ( 4 sec ⁡ t + tan ⁡ t ) = \frac{d}{dt}\left(4\sec t+\tan t\right)= d t d ( 4 sec t + tan t ) =

sec ⁡ t ( 4 tan ⁡ t + sec ⁡ t ) \sec t\left(4\tan t+\sec t\right) sec t ( 4 tan t + sec t )

4 tan ⁡ t + sec ⁡ t 4\tan t+\sec t 4 tan t + sec t

4 sec ⁡ t + tan ⁡ t 4\sec t+\tan t 4 sec t + tan t

tan ⁡ t ( 4 sec ⁡ t + tan ⁡ t ) \tan t\left(4\sec t+\tan t\right) tan t ( 4 sec t + tan t )

d d t ( 4 sec ⁡ t + tan ⁡ t ) = \frac{d}{dt}\left(4\sec t+\tan t\right)= d t d ( 4 sec t + tan t ) =

sec ⁡ t ( 4 tan ⁡ t + sec ⁡ t ) \sec t\left(4\tan t+\sec t\right) sec t ( 4 tan t + sec t )

4 tan ⁡ t + sec ⁡ t 4\tan t+\sec t 4 tan t + sec t

4 sec ⁡ t + tan ⁡ t 4\sec t+\tan t 4 sec t + tan t

tan ⁡ t ( 4 sec ⁡ t + tan ⁡ t ) \tan t\left(4\sec t+\tan t\right) tan t ( 4 sec t + tan t )
