Answer:
Step-by-step explanation:
The end behavior of this function is the same as that of y = -x^2: the graph starts in Quadrant III and continues in Quadrant IV; the shape is roughly that of an upside-down parabola.
(f + g)(x) = 7x + 6 + 4x² = 4x² + 7x + 6
The notation given means to add the rules of f(x) and g(x), and since there are no like terms, your answer is 4x² + 7x + 6
