Answer: Choice A</h3>
-425 < 212
==========================================================
Explanation:
Draw a horizontal number line with negative numbers on the left, and positive on the right. Therefore, -425 is to the left of 212. In turn this means -425 is smaller than 212
Alternatively, draw a vertical number line. Think of 0 as the ground, positive numbers above ground, and negative numbers below ground. With 212 higher than -425, we know that 212 is larger than -425; i.e. -425 is smaller than 212
Answer: A. 2x2 - 3x - 8
Just subtract the functions and combine like terms
(f - g)(x) = f(x) - g(x)
(f - g)(x) = 2x^2 - 5 -(3x + 3)
(f - g)(x) = 2x^2 - 5 - 3x - 3
(f - g)(x) = 2x^2 - 3x - 8
