Referring to y = x + 2, the set of values assigned to x is called the —

- The set of values assigned to s is called the domain.

Explanation :-

For the given equation y= x+2, x is a independent variable where y is a dependent variable .

The given equation representing a function y=f(x)=x+2

We know that for every function f(x), the set of values assigned to x is called the domain and the set of corresponding outputs y for each value of x  is called the range.

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
