Given the following functions f(x) and g(x), solve for (f ⋅ g)(2) and select the correct answer below: f(x) = 3x2 + 2 g(x) = x − 8 a. -42 b. -84 c. 42 d. 84

For this case we have the following functions:
 
 Multiplying both functions we have:
 
 By doing distributive property we have:
 
 Finally, by rewriting we have:
 
 Then, evaluating for x = 2 we have:
 
 
 B. -84
 

I'm a bit puzzled here because they did not provide you with any measures of the other angles, so i am unable to provide a theorem or postulate to support my answer, but i'd say 90 degrees because it looks closer to a right angle than anything.
