Question

Decide whether the table represents a linear or exponential function circle with a linear exponential then write the function formula.​

Answer 1

This function starts at
`(0,3)`, so we have
`f(0)=3`.

Then, every time
`x` increments by 1,
`y` doubles. This is typical of exponential functions. In linear functions, every time
`x` increments by 1,
`y` increments by a fixed amount (the slope of the function).

So, this is an exponential function, and the equation is

`f(x)=3\cdot 2^x`
