Question 127190: I need help to perform the indicated operation given the functions
f(x) and g(x):
f(x)=2x-9 f(x)=4x-4
I need help finding (f-g)(x)

You can put this solution on YOUR website!
Remember, (f-g)(x) translates to f(x)-g(x)


f%28x%29-g%28x%29 Start with the given functions


%282x-9%29-%284x-4%29 Plug in f%28x%29=2x-9 and g%28x%29=4x-4


2x-9-4x%2B4 Distribute the negative


-2x-5 Combine like terms


So this shows us that %28f-g%29%28x%29=-2x-5
