Please help me and thank you

Question

Y=3x2^x+1 I need help knowing what numbers to plot onto the graph after I got the 5 numbers/ fractions for my table thing cause i don't understand where to put what on the graph In order to get it right and thanks

Answer 1

For y = 3(2)^(x+1) 

 

Try plotting these points:

Let x = 0, y = 3(2)^1 = 6

Let x = 1, y = 3(2)^2 = 3(4) = 12

Let x = -1, y = 3(2)^0 = 3(1) = 3

 

If you use the same method to solve for x = 2 and x = -2, they should also fall on the line drawn with the previous points.  

Please let me know if you need a more comprehensive explanation.
