Answer:
True
Step-by-step explanation:
(x + 4)² = (x + 4) (x + 4)
x² + 4² = x² + 16
The sum of the function will be (r – s)(x) = –2x² + x – 3, The difference of the function will be (r – s)(x) = –2x² + x – 3, and The product of the function will be (r × s)(x) = 2x³ – 6x².
The complete question is attached below.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The functions are given below.
r(x) = x – 3
s(x) = 2x²
The sum of the function will be
(r + s)(x) = x – 3 + 2x²
(r + s)(x) = 2x² + x – 3
The difference of the function will be
(r – s)(x) = (x – 3) – 2x²
(r – s)(x) = –2x² + x – 3
The product of the function will be
(r × s)(x) = (x – 3) (2x²)
(r × s)(x) = 2x³ – 6x²

Answer:
Sin (270º)= -1
Cos (270º) = 0
Tan (270º) = -∞
Sin (330º) = -0.5
Cos (330º) = = 0.8660
Tan (330º) = - = -0.57735
