If f(x) = 2x^2 + y, and f(2) = 50, what is the value of f(5)? Choose the correct choice from the following choices
A) 104
B) 60
C) 92
D) 50
E) 25

Rationale: "f ( x ) = 2 x ^ 2 + y f ( 2 ) = 50 = > 2 * ( 2 ) ^ 2 + y = 50 = > 8 + y = 50 = > y = 42 f ( 5 ) = 2 * ( 5 ) ^ 2 + 42 = 92 answer c"
Answer: C
