Question

Read the information given below and answer the questions that follow:
A, S, M and D are functions of x and y, and they are defined as follows:
A (x, y) = x + y
S (x, y) = x – y
M (x, y) = xy
D (x, y) = $\frac{x}{y}$ where y is not equal to 0.

What is the value of M(M(A(M(x, y), S(y, x)), x), A(y, x)) for x = 2, y = 3?

• A. 50
• B. 140
• C. 25
• D. 70

Answer 1

The correct option is D 70

M (M (A (M (x, y), S (y, x)), x), A (y, x))

M (M (A (6, 1), 2), A (3, 2))

M (M (7, 2), A (3, 2))

M (14, 5) = 70
