Given that f(x) =<br> X + 3<br> 2 <br> a) Find f(2)<br> b) Find f'(x)<br> c) Find f"(12)
joja [24]

Answer:

Step-by-step explanation:

Unclear.  Did you mean f(x) = 2^(x + 3)?  If so, the parentheses are mandatory.

Assuming that f(x) = 2^(x + 3) is correct, then:

a) f(2) = 2^(2 + 3) = 2^5 = 32

b) f'(x) = 2^(x + 3)*(x + 3)' = 2^(x + 3)(1) = 2^(x + 3)

c) f"(x) = 2^(x + 3) (same as in (b)), so that:

   f"(12) = 2^15
