Tan(a/2) = sin a / (1 + cos a)
tan(45/2) = sin(45) / (1 + cos(45)) = (1/√2) / (1 + 1/√2) = (1/√2) / (√2 + 1)/√2 = 1/(√2 + 1) = (√2 - 1)

In order a0->a5: 1/3, 1, 3, 9, 27, 81
All you're doing is plugging the x-value in. So for a2, x=1, so y=3¹ which means y=3.
Answer: Down
Step-by-step explanation:
We know that the graph of y
=
x
4 has both arms pointing up.
Now, since the leading coefficient of f
(
x
) is negative, both arms are pointing down. Thus the right side is pointing down.
