If the function f(x) is defined for all real numbers x as the maximum value of 2x + 2 and 12 + 3x, then for which one of the following values of x will f(x) actually equal 2x + 2 ?
Options:
A) –4
B) –8
C) –11
D) –13
E) –19
Since f(x) defines maximum of 2x + 2 and 12 + 3x,   to find those x when 2x+2 has greater value,   2x + 2 &gt; 12 + 3x   or x &lt; -10   Only value that satisfy this is -11.   Answer is (–11),
