Answer: 0 ≤ y < ∞
Step-by-step explanation:
First, let us graph the function. See attached.
-><em> If I graphed the formatting of the square root sign incorrectly, please let me know so I can fix the answer.</em>

The range of the function is all of the function's output values. In this case, all of the y values.
0 ≤ y < ∞
Answer:
C
Step-by-step explanation:
Region A has solutions going down
Region B has solutions between A and C
Region C has solutions going upwards.
There are no solutions that are in common.
C is the answer
The value of cos 67.4° is 5/13.
According to trigonometric identities used in mathematics, sin of an angle is equal to cos of 90 - the given angle. Mathematically, this means that, suppose we have an angle x, then-
sin(90 - x) = cos x
Here, we are given that sin 22.6° = 5/13. As we can observe that (90 - 67.4) is equal to 22.6, and we need to find the value of cos 67.4° only. Thus we can write the given equation as follows-
sin22.6° = sin(90 - 67.4°)
= cos 67.4°
Thus, sin 22.6° = cos 67.4°
Hence, cos 67.4° = 5/13
Thus, the value of cos 67.4° comes out to be 5/13.
