Find the leading term of the polynomial function \(f(x) = 3x^5 - 4x^4 + 2x^3 - x + 5\)

Step 1 ：The leading term of a polynomial is the term with the highest power of the variable, in this case \(x\).

Step 2 ：In the given polynomial function \(f(x) = 3x^5 - 4x^4 + 2x^3 - x + 5\), the term with the highest power of \(x\) is \(3x^5\).
