For this case we have that by definition:
[tex](fg) (x) = f (x) * g (x)[/tex]
So:
[tex](fg) (x) = (3x ^ 2 + 5) (x-2)[/tex]
We apply distributive property that states that:
[tex](a + b) (c + d) = ac + ad + bc + bd[/tex]
In addition, we take into account that:
[tex]+ * - = -[/tex]
[tex](fg) (x) = 3x ^ 3-6x ^ 2 + 5x-10[/tex]
Answer:
[tex]3x ^ 3-6x ^ 2 + 5x-10[/tex]
Option B
Answer:
(fg)(x) = 3x³-6x²+5x-10
Step-by-step explanation:
We have given two functions.
f(x)=3x²+5 and g(x)=x−2
We have to find (fg)(x).
The formula to find fg is :
(fg)(x) = f(x) × g(x)
Putting values in above formula, we have
(fg)(x) = (3x²+5)(x-2)
(fg)(x) = 3x²(x-2)+5(x-2)
(fg)(x) = 3x³-6x²+5x-10 which is the answer.
