So,here we have a graph.For every unit of 1(x axis),the unit of the previous y axis is multiplied.

Like this.

(0,2),(1,4),(2,8),(3,16)........

I don't know how the formula will be,and had never seen this kind of graph.

The y seems to be a geometric sequence,on which we can use, ## ar

So 2 x 2

n is the value of x.For every value of x,we can now find the value of y.

So how can we find the general formula of the graph?Is it ## y=2 x 2

I don't know why LaTeX is not working,Help please.

^{(n-1)}## .r is 2.a is 2So 2 x 2

^{(n-1)}n is the value of x.For every value of x,we can now find the value of y.

So how can we find the general formula of the graph?Is it ## y=2 x 2

^{(x-1)}## ? I don't think so,If the x values started with 1,it's possible.I don't know why LaTeX is not working,Help please.
