Question

What is the minimum y value on the graph of y = sinx - 6?

-7
-5
5
7

Answer 1

Answer:

The correct answer option is -7.

Step-by-step explanation:

We are asked to determine the minimum value of y on the graph of $y = sin x - 6$.

$y' = cos(x) = 0$

$x = arccos(0) = \pm\frac{\pi }{2} +2k\pi$ where 'k' is any integer.

So, $y = sin ( \frac { \pi} { 2 } ) - 6 = 1 - 6 = -5$ (it is the absolute minimum value)

and $y=sin(\frac{-\pi}{2}+2\pi )-6 = sin(\frac{3\pi}{2})-6$ = -7 (absolute minimum y value)

Answer 2

Answer:

The correct answer option is -7.

We are asked to determine the minimum value of y on the graph of . where 'k' is any integer.

So,  (it is the absolute minimum value)and  = -7 (absolute minimum y value)
