The equation y = ax*b* + c produces the
following (x, y) coordinate pairs: (0, 2),
(1, 7), and (2, 42). What is the value of abc? Choices:
A) 10  B) 20  C) 30  D) 40  E) 60
To begin, plug x = 0 and y = 2 into the equation y = axb + c. Note that the first term   drops out:   2 = a(0)b + c   2 = c   Now you can substitute 2 for c in the original equation, giving you y = axb + 2. Next, plug in   x = 1 and y = 7. Notice that everything drops out except for the coefficient of the first term:   7 = a(1)b + 2   5 = a   You can now substitute 5 for a in the equation, giving you y = 5xb + 2.=

2   and y= 42:   42 = 5(2)b + 2   40 = 5(2)b   8 = 2b   23 = 2b   3 = b   Finally, you can see that abc = (5)(3)(2) = 30.   correct answer 30)30
