See an explanation below:

$(f + g) (x) = f (x) + g (x) = x^{2} + 10 + x - 3$ $(f + g)(x) = f(x) + g(x) = x^2 + 10 + x - 3$

$(f + g) (x) = x^{2} + x + 10 - 3$ $(f + g)(x) = x^2 + x + 10 - 3$

$(f + g) (x) = x^{2} + x + 7$ $(f + g)(x) = x^2 + x + 7$

If f(x)=x2+10f(x) = x^2 + 10; g(x) = x – 3, what is (f + g)(x)?
