Answer:
-1 ≤ y ≤ 0
Step-by-step explanation:
here, we simply want to know the range of values for sin x over the given interval
The range of values for sin x are simply the values in which y will take over the given interval of x
let’s start with the value sine (-pi)
We have this as;
0
And the value of sin (0) = 0
Recall, between -pi and 0, we have (-pi/2)
so sin (-pi/2) = -1
Thus, we have the correct range of values as;
-1 ≤ y ≤ 0
