Example of Zero to the Power of Zero
Consider the real polynomial function:
- $y = \paren {x + c}^n$
for $n \in \N, c \in \R$.
By the binomial theorem, $y$ contains a term of the form:
- $\dbinom n n x^{n - n} c^n$
If we did not define $0^0 = 1$, $y$ would have a discontinuity at $x = 0$.
This would contradict Real Polynomial Function is Continuous.
