To find (f + g)(x), you need to add the two functions f(x) and g(x).
Given:
– f(x) = -3x² + 8x
– g(x) = 3x
We can combine these functions by adding their expressions:
(f + g)(x) = f(x) + g(x)
= (-3x² + 8x) + (3x)
= -3x² + 8x + 3x
= -3x² + 11x
So, (f + g)(x) = -3x² + 11x.
This is the polynomial in simplest form. If you have any further questions or need more details, feel free to ask!
