Question 1118872: given the functions f(x) = 1-3x^2 and g(x) = sqrtx-1, find the functions (f+g) , (f-g), (f*g), (f/g) and their corresponding domains.
Answer by josgarithmetic(39620) (Show Source): You can put this solution on YOUR website!
g(x) is how?
or ?

LATER: You wanted .

I will do only one of the four examples.

and you might leave the function in this form, or 'simplify' to .

DOMAIN: Obviously if real numbers, the factor needs to be such that is NOT negative; so is the domain.
