Question

For the given functions f and g, find the requested function and state its domain. f(x) = x - 9 ; g(x) = 9 x 2 Find f + g.

Answer 1

f + g=9x^2 +x-9

The domain is all real values

Explanation:

f(x) = x - 9

g(x) = 9 x^2

f + g=x-9+9x^2

= 9x^2 +x-9

The domain is the values that x can take

The domain is all real values
