To graph y = -cosx,

shift y = cosx left 1 on the x-axis
shift y = cosx up 1 on the y-axis
reflect y = cosx over the x-axis
reflect y = cosx over the y-axis

reflect y = cos x over the x-axis

Step-by-step explanation:

When a function is reflected over the x-axis, the transformation is:

y = -f(x)

If it were reflected over the y-axis, the transformation would be:

y = f(-x)

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.
