Question

What is the function represented by the following graph key points are (-1,1/3),(0,1),(1/3),(2,9)

Answer 1

Given the points:

(-1,1/3),(0,1),(1/3),(2,9)​

the graph of the points is as following:

so, the graph represents exponential function

We can note that:

The y values represents geometric sequence

`1,3,9,\ldots`

so, the function will be:

`y=f(x)=3^x`
