Let f and g be the function from the set of integers to itself, defined by f(= 2x + 1 and g(= 3x + 4. Then the composition of f and g is ________.
A. 6x + 9
B. 6x + 7
C. 6x + 6
D. 6x + 8
Answer:A
Let f and g be the function from the set of integers to itself, defined by f(= 2x + 1 and g(= 3x + 4. Then the composition of f and g is ________.
A. 6x + 9 B. 6x + 7 C. 6x + 6 D. 6x + 8
Explanation: The composition of f and g is given by f(g(x)) which is equal to 2(3x + 4) + 1.
