Question

For the given functions f and g, find the requested function and state its domain.
-f(x)= 4x - 9; g(x)= 6x - 2Find f - g.
A)(f - g)(x)= -2x - 7; all real numbers 
D)(f - g)(x)= 2x + 7; all real numbers

Quizplus · Accepted Answer

To find f - g, we simply subtract the expression for g(x) from the expression for f(x):
f - g = (4x - 9) - (6x - 2) = -2x - 7
The domain of f - g is all real numbers, as both f(x) and g(x) have a domain of all real numbers.
