ANSWER
d. The set of all real numbers
EXPLANATION
The basic cosine function ,
is continuous everywhere.
The function is defined for all real values of x.
The domain is the set all values of x that will make the function defined.
The domain is all real numbers.
The correct choice is D.
Answer:
The equation is set up wrong
Step-by-step explanation:
Answer: The answer is (d)
Step-by-step explanation: Given equation to be factored is
The given expression is quadratic, so we can factor it into two linear factors, by using the following factorisation rule.
So, the given equation can be factorised using the above rule. The factorisation is as follows.
Thus, the correct option is (d).
