Determine if f(x) = x2 - Fx is a plarynomial function. If it is, state the degree and the leading coefficient. If not, state why.
8.
1
Yes. The degree is and the leading coefficient is -1.
5
No. There is an exponent on a variable x that is not a whole number.
Yes. The degree is 2 and the leading coefficient is 1.
No. The leading coefficient is not a whole number.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
