Given the function:
f(x) = x^2 - 2x
g(x)= 6x + 4
Determine (f + g) (x) =
Solution:
In order to determine the answer, we simply put the given functions in one equation separated with an addition sign as the condition dictates.
=( x^2 - 2x) + (6x + 4)
Combine like terms.
=x^2 - 2x + 6x + 4
=x^2 + 8x + 4
Final answer:
x^2 + 8x + 4
