To find the composite function 2f(x) - 4g(x), we need to substitute f(x) and g(x) into the given function.
Step 1: Substitute f(x) = x^2 + 4x - 1 and g(x) = 2x - 4 into the composite function.
2f(x) - 4g(x) = 2(x^2 + 4x - 1) - 4(2x - 4)
Step 2: Simplify the expression.
= 2x^2 + 8x - 2 - 8x + 16
= 2x^2 + 14
Therefore, the composite function 2f(x) - 4g(x) is equal to 2x^2 + 14.
By substituting the given functions f(x) and g(x) into the composite function and simplifying the expression, we were able to find the result.
