Answer:
its the first you were correct
Step-by-step explanation:
Ive had this question before
<span>(g o f)(x) is the same as g(f(x))
</span>
f(x) = x+1 g(x) = x² - x
g(f(x)) = g(<span>x+1)
</span>Note g(x) = x² - x, therefore g(x+1) would be that anywhere we see x in g(x) we replace it with (x+1)
g(x) = x² - x
g(x+1) = (x+1)² - (x+1) = x² + 2x +1 - x - 1 = x² + 2x-x +1 -1 = x² + x
Therefore (g o f)(x) = x² + x
Hey there!
To start, when you perform (f+g)(x), you are adding the functions together. This would mean, you would add 4x+9 to 4x^2. This should look like this:
(4x+9)+(4x^2)
Because there are no like terms, your final answer would be 4x+9+4x^2 or the last answer choice.
Hope this helps and have a marvelous day! :)
