Find f(—2) for f(x) = 2 • 3^x.
A. 1/18
B. 2/9
C. -18
D. -36

Answer:
B. 2/9
Step-by-step explanation:
You just need to replace x with -2:
F(-2) 2*[tex]3^{-2}[/tex] the second power of 3 is 9 and since there's a minus sign in front of 2 we turn the value upside down so it's 1/9
f(-2) = 2*1/9
f(-2) = 2/9
