# Given f(x) = x +2 and g(x)= 2x^2-4x+2, how do you find f(x)+g(x)?

$f + g = 2 {x}^{2} - 3 x + 4$
Hence the domain of $D f = R$ and $D g = R$ where R is the set of real numbers the sum of the two functions is defined which means it exists in real numbers.Hence the sum is
$f + g = x + 2 + \left(2 {x}^{2} - 4 x + 2\right) = 2 {x}^{2} - 3 x + 4$
