Question

If f(x) = 5x2 – 8x + 13 and g(x) = 6x – 5, what is f(x) + g(x)?

Answer 1

To add two functions, you simply sum the terms of the two functions.

Answer 2

i dont know how to do that

Answer 3

Yes you do. You just add together all of the terms in function f(x) with all of the terms in function g(x). So if in an example, f(x)=2x^2-5x+6, and g(x)=2x-4, you would just add those terms all together, 2x^2-5x+6+2x-4, then simplify by combining like terms, to get 2x^2-3x+2. Now do that with your two functions.
