Solution:
from; f(2)=3
f(2n) nf(2)
(3)(n)
therefore :
f(32)=f(2.16)
f(32)=16f(2)
f(32)=(16)(3)
f(32)=48 final answer

Answer:
-6
Step-by-step explanation:
distribute.
5x-10-9=-7+7x
get variables on the same side by +/- on both sides of the equation
5x-10-9=-7+7x
-5x. -5x
-19=-7+2x
+7 +7
-12=2x
divide to get x by itself
-<u>12=2x</u>
2. 2
x= -6
