If the function f(x) is defined for all real numbers x as the maximum value of 2x + 4 and 16 + 6x, then for which one of the following values of x will f(x) actually equal 2x + 4 ?
Choose the correct answer
A) –4
B) –5
C) –6
D) –7
E) –9
Since f(x) defines maximum of 2x + 4 and 16 + 6x,   to find those x when 2x+4 has greater value,   2x + 4 &gt; 16 + 6x   or x &lt; -3   Only value that satisfy this is -4.   –4nswer is (–4),
