To find the degree of the polynomial \( f(x) = -4 + 6x^5 - 2x^3 + 2x^4 - 10x^2 \), we will first put it into standard form, where the terms are arranged in descending order of their degrees.
Here are the terms of \( f(x) \):
\( 6x^5 \)
\( 2x^4 \)
\( -2x^3 \)
\( -10x^2 \)
\( -4 \)
Putting these into standard form, we have:
\[
f(x) = 6x^5 + 2x^4 - 2x^3 - 10x^2 - 4
\]
Now, we identify the leading term. The leading term is the term with the highest degree, which is \( 6x^5 \).
Thus, the leading term is \( 6x^5 \).
To find the degree of the polynomial, we look at the exponent of the leading term:
