Answer:
Domain = ( -∞ , ∞ )
Range = ( ∞ , ∞ )
Step-by-step explanation:
A function is given to us and we need to find the domain and range of the given function .
<u>The </u><u>function</u><u> </u><u>:</u><u>-</u><u> </u>
Definitions :-
- <u>Range </u>:- The range is the set of all valid y values .
- <u>Domain</u> :- All real numbers except where the expression is undefined.
In this case, there is no real number that makes the expression undefined. Therefore the domain will be :-
<u>Domain</u><u> </u><u>:</u><u>-</u><u> </u>
or
<u>Range </u><u>:</u><u>-</u><u> </u>
or

<span>5x + 2y = 20
put x=0.3
5(0.3) + 2y = 20
2y = 20-1.5
2y = 18.5
y = 9.25

Answer:
x=(-2)
Step-by-step explanation:
subtract 4x from 2x
-6+7=1 4-2=2 subtract 1 from 2
-2x=1 x=-2
Answer:
cos P = 71.09
Step-by-step explanation:
cos = 
cos P = 
cos P = 0.324
cos-1 of 0.324 is 71.09
cos P = 71.09
