Step 1

Refer to the question for the given function f(x) = 4x^{2}+12x-40 and g(x) = x + 5. we need to calculate the (f+g)(x), (f-g)(x) , (fg)(x) and f/g (x) and also their domain.

Then to find (f+g)(x),

Step 2

The domain of the function is that value of x for which the function is defined. And (f+g)(x) = 4x^{2}+13x-35 is a polynomial function so it defined for all value of x.

That is,

Step 3

Similarly, for (...
