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(n-1) ## .r is 2.a is 2
So 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.
