Linear and exponential

Question

Hi Show me how to do this problem y=3(2)* on a graph please can’t figure it out.

Answer 1

I'm assuming that your problem is y = 3(2)^x where the exponent is the variable x. If we built a table, would get something like this:

x | y

-- |-----

0 | 3

1 | 6

2 | 12

-1 | 1.5

-2 | 0.75

Because:

3(2)⁰ = 3*1 = 3

3(2)¹ = 3*2 = 6

3(2)² = 3*4 = 12

3(2)^-1 = 3*1/2 = 1.5

3(2)^-2 = 3*1/4 = 0.75

So, graphing this we get:
