Answer:
Solution :
Step-by-step explanation:
Let's apply trivial identities here. We know that cos(-π / 4) = √2 / 2, sin(-π / 4) = - √2 / 2, cos(-π / 2) = 0, sin(-π / 2) = - 1. Let's substitute those values,
= ÷
= ÷
= ÷ = ÷ =
As you can see your solution is the last option.
Answer: B. (-4, 0)
<u>Step-by-step explanation:</u>
The question is: when is the <u>function</u> constant?
function is also called f(x), which is also called "y".
So the question is asking: when is the y-value constant?
the y-value is constant (not increasing or decreasing) between x = -4 and x = 0. So the interval is (-4, 0)
