Question

Can the exponential function below be written as a polynomial function? f (x)=2^x

Answer 1

1) Since we have the function:

`f(x)=2^x`

And a polynomial, by definition, is written as:

`P(x)\text{ = }a_nx^n+.\ldots.a_0x^0`

2) Then No, we can't rewrite it as a polynomial function since there are no other constants and coefficients and this exponential function is written as simple as that.
