Find $f - g$ and $f \cdot g$. Then, give their domains using interval notation.
$(f - g)(x) = 
$
Domain of $f - g$: 
$(f \cdot g)(x) = 
$
Domain of $f \cdot g$:

Suppose that the functions f and g are defined as follows.

f(x) = (1)/(2x^2 + 5)

g(x) = 5x^2 + 3

Find f - g and f · g. Then, give their domains using interval notation.
(f - g)(x) =
Domain of f - g:
(f · g)(x) =
Domain of f · g:
