Answer:
A. the leading coefficients of f (x) and g (x) are opposites
Step-by-step explanation:
A. the leading coefficients of f (x) and g (x) are opposites
A quadratic function in its generic form is:
f (x) = ax2 + bx + c
g (x) = dx2 + ex + f
The sum of the functions is:
(f + g) (x) = (a + d) x2 + (b + e) x + (c + f)
For the function to be linear necessarily:
a = -d
Answer:
Nope. Moltiplication (and thus divisions) has to be done before any addition or subtractions, unless parenthesis indicate otherwise.
