Answer 2

The numeric value of the expression is: (f - g)(144) = 0.

----------------

• The function f(x) is given by: $f(x) = \sqrt{x} + 12$
• The function g(x) is given by: $g(x) = 2\sqrt{x}$
• The subtraction of the functions f(x) and g(x) is given by:

$(f - g)(x) = f(x) - g(x) = \sqrt{x} + 12 - 2\sqrt{x} = 12 - \sqrt{x}$

• At x = 144, the numeric value of the subtraction function is given by:

$(f - g)(144) = 12 - \sqrt{144} = 12 - 12 = 0$

Thus, (f - g)(144) = 0.
