First, let's understand what we're doing. We are dealing with subtracting functions. Always be sure to know what you're subtracting by what - you don't want to misinterpret the situation and mess up over a minor error.
Now, let's get to the problem.
f(x) = 4x + 1 g(x) = x^2 - 5
Find (f - g)(x).
By "Find (f - g)(x)", we mean to subtract f(x) by g(x).
Remember what f(x) is and what g(x) is.
So, let's set up our equation.
4x + 1 (Remember to subtract like-terms) -x^2 + 5 —————— -x^2 + 4x + 6 is your solution.
