Plato which restricted domain would allow you to define the inverse cosine function?

0 ≤ x ≤ π

Step-by-step explanation:

In order to define the inverse cosine functions, the domains of the cosine functions are restricted.

One major condition to define an inverse of a function is that the original function must be one‐to‐one which means that one value from the domain should correspond to only one value in the range.

So we have a restriction that is placed on the values of the domain of the cosine function which is the following:

0 ≤ x ≤ π

i believe the answer is the polygon, heptagon.

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).
