Answer:
can you explain it more and then I will know the answer
Assuming you want the range of
-4cos(2x)
the range of the cosine function is -1 to 1. When that is scaled by a factor of -4, it becomes 4 to -4.
The range of F(x) is [-4, 4] in interval notation.
_____
If you want the range of
F(x) = -4cos²(x)
that range will be -4×[0, 1] = [-4, 0].
Answer:
24
Step-by-step explanation:
Given two fractions
and 
Factor the denominators of both fractions:

You can see that two digits 2 are the same in both denominators and there are two more factors: 2 in number 8 and 3 in number 12.
Thus, the least common denominator for
and
is

Answer:
the answer is b
