What is “ f(x) = 2x^2- 32x” in standard form if it has one?

Most textbooks interpret standard form of a quadratic function to be as follows:

f(x) =

In the function f(x) = , notice we do not have a value for "c". Just place a "0" in for the c and you have standard form.

the criteria for standard form:
1. All like terms are combined
2. Degree must drop from left to right
3. The leading coefficient cannot be equal to zero.
