How many possible values for y are there where y= Cos -1 0

Mathematics

6 0

Answer:

B) 1 possible value

FOR THIS SPECIFIC INSTANCE

Step-by-step explanation:

If it is Cos -1 (0) and cos is capitalized, that means it is a function and you apply restrictions. Based on the restrictions you get one possible value (I think the value is pi/2)

However, if the problem is cos -1(0) with no capitalization, it is a relation meaning values are infinite because of repetitions. The answers would be pi/2 and 3pi/2 and both would be added/subtracted by 2n(pi).

Are both a function or not ?

Ganezh [65]

Answer:

Here

Step-by-step explanation:

Domain : (-∞,∞)

Range : (-∞,∞)
Both functions generally are the same and yes both are functions.

One is the data set of a function and one is the equation...
