Question

Fill in the table for the exponential function given f(x)=3(2)^n

Answer 1

A = 3/2

B = 3

C = 6

D = 12

Explanation:

Simply plug it in. When you have a negative exponent, you basically switch the sign of the exponent and put a one over the number itself.

• So we have 2^-1. This is the same as
  `3((1)/(2^1)) =3( (1)/(2)) = (3)/(2)` = a

• Now do
  `3(2^0) = 3` = b

• Then do
  `3(2^1) = 6` = c

• Finally do
  `3(2^2) = 12` = d
