is it A or B?

please, I want to work.. @mathway @Elsa213 @ganeshie8

Make x=-3 in g(x). What's your answer?
OpenStudy (anonymous):
g(x) = x − 2
g(x)=-5

Divide f(x) by g(x).
OpenStudy (anonymous):
f(x) = 6x + 8
f(x)=-10
OpenStudy (anonymous):
-10/-5, or -2
OpenStudy (anonymous):
i meant 2
OpenStudy (anonymous):
not negative

Substitute all x=-3.\[\frac{ 6x+8 }{ x-2}\]
OpenStudy (anonymous):
-10/-5

haha its okay!Given the following functions f(x) and g(x), solve for (f ⋅ g)(2) and select the correct answer below:
f(x) = 3x^2 + 2
g(x) = x − 8
−42
−84
42
84
OpenStudy (anonymous):
Or just substitute x=2 in f(x).
OpenStudy (anonymous):
then substitute x=2 in g(x)
OpenStudy (anonymous):
then multiply them together

3*2^2 + 2*2 − 8
6^2+2*-6
OpenStudy (anonymous):
\[f(x)=3(2)^2+2\]\[g(x)=2-8\]
OpenStudy (anonymous):
14*-6
OpenStudy (anonymous):
Multiply them.
OpenStudy (anonymous):
-84, or B?
