Directions: Read the following information to answer the question.
The following function are defined for any two, distinct, non-zero integers X and Y.
f ( X, Y) = |X| x Y2
g (X, Y) = X2 x |Y|
h (X, Y) = (X2 + Y2)/2
j (X, Y) = X/2 + Y/2
Which of the following gives you (X + Y)2?
Directions: Read the following information to answer the question.
If f(X) = 1 – X, 0 ≤ X ≤ 2
X – 1, 2 ≤ X V 3
1, 3 ≤ X ≤ 5
then, find f(1/2) + f(40/16).
f(1/2) = 1 - ½ = ½ = 0.5
f(40/16) = f(2.5) = 2.5 – 1 = 1.5
f(1/2) + f(40/16) = 0.5 + 1.5 = 2
Directions: Read the following information to answer the question.
y = mx + c
m = c
⇒ y = mx + m
⇒ -5 = -3m + m
⇒ m = 5/2
y = 5/2x + 5/2
⇒ 2y = 5x + 5
⇒ 2y – 5x = 5
