Question

If f(x) and g(x) are quadratic functions but (f + g)(x) produces the graph below, which statement must be tru

Answer 1

The leading coefficients of f(x) and g(x) are Opposites.

Option A is the correct option.

Explanation:

As the graph of ( f + g ) ( x ) is a line. So, ( f + g ) ( x ) is linear which means x² of f ( x ) and x² of g ( x ) get cancelled on adding . They must be equal and opposite in sign.

So, Option A is correct.

Hope this helps..
