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)

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

no this is a nonlinear negative
