Answer:
(f + g)(x) = – 3x^2 + 5x - 8
Step-by-step explanation:
(f + g)(x) = f(x) + g(x)
= 5x^2 + 9x – 4 + (– 8x^2 – 3x – 4)
= 5x^2 + 9x – 4 – 8x^2 – 3x – 4
Combine
= – 3x^2 + 5x - 8
<em>The result can be shown in both exact and decimal forms. </em>
<em>Exact Form: </em>
<em>4 e + 21 </em>
<em>Decimal Form: </em>
<em>31.87312731 …</em>
