Question

If f(x)=-4x^2-6x-1 and g(x)=-x^2-5x+3 find (f+g)(x) PLS ANSWER FAST!

Answer 1

When you do (f+g)(x), all you have to do is take both functions and add them to each other. It should look like this when you set it up:
$(f + g)(x) = (4x {}^{2} - 6x - 1) + (x {}^{2} - 5x + 3)$
Then just add like terms and you should get:
$(f + g)(x) = 5x {}^{2} - 11x + 2$
Hope this helped.
