Step 1 :Let's consider the function \(g(x)=25-x^{2}\).
Step 2 :The leading term of a polynomial is the term with the highest degree. In this case, the leading term of \(g\) is \(-x^{2}\).
Step 3 :The degree of a polynomial is the highest power of the variable in the polynomial. Therefore, the degree of \(g\) is \(2\).
Step 4 :The leading coefficient of a polynomial is the coefficient of the leading term. Here, the leading coefficient of \(g\) is \(-1\).
Step 5 :\(\boxed{\text{i. The leading term of } g \text{ is } -x^{2}}\)
Step 6 :\(\boxed{\text{ii. The degree of } g \text{ is } 2}\)
Step 7 :\(\boxed{\text{iii. The leading coefficient of } g \text{ is } -1}\)
