Answer:
Yup if you have 8+8=14 then 8+8-1=-1
Answer:C
1/1+cos(x)
Step-by-step explanation:
So We Know That tan(x) Equals

We Can Use Logic, We Know That Anything That Makes The Denominator 0, Will Not Work, So We Need To Know What Makes Sin(x) equal to 0 and Cos(x) equal to 1 or -1 BUT NOT 0


We Didn't Want Cosine To equal Zero Because Then We Get

THE ANSWER IS C : -360°,-180°,0°,180°,360°
D.
Explanation: a function can be described as something that has only one output for each input. So an X or input can only have ONE output.
Ex. (2,6) (2,8) would NOT be a function because there are two 2’s with two different outputs meaning it’s not a function.
