Answer 1

(f - g)(x) = 9x - 5

Answer 2

This question is regarding composite functions. The two given functions are f(x) = 5x + 1 and g(x) = 2(3 - 2x). The question is to find the composite function (f - g)(x). To do this, you firstly take away the function g(x) from f(x). The key is to apply subtraction operations to both functions and bind them together.
Let's do it step by step:
Step 1: Write down the equations: f(x) = 5x+1 and g(x) = 2(3-2x).
Step 2: Open the bracket for g(x): g(x) = 6 - 4x
Step 3: The composite function (f - g)(x) = f(x) - g(x), You substitute for every occurrence of f and
g based on the given equations.
Step 4: (f - g)(x) = (5x+1) - (6 - 4x)
Step 5: resolve confusion of negative value for later variable after subtraction
(f - g)(x) = 5x + 1 - 6 + 4x
Step 6: Group the x terms together and constants together.
