Answer:
Domain All real x.
Range f(x) >= 1.
Step-by-step explanation:
The domain is all real numbers.
|x| is always positive.
At x = 0:
f(x) = |0| + cos 0
= 1 which is the minimum value.
The answer is 1/3
1/3 + 1/3 + 1/3 equals 1
which is the same as 1/3 times 3
Answer:
because in the bottom eqution it shows us x-3=y therefor we could re-write the top equation as x+x-3=11
Acute is less then 90 degrees, right is 90 degrees, and obtuse is more then 90 degrees.
