Answer:
See below.
Explanation:
The degree is simply the number of the exponent (or the sum) and the coefficient is simply the number in front of the term.
First Term: -7; Deg=0, Co=-7.
-7 is the same as saying -7x^0. Thus, the degree is 0.
Second Term: -x^4; Deg=4, Co=-1
-x^4 is the same as saying -1(x^4). Thus, the degree is 4 while the coefficient is -1.
Third Term: -5x^3; Deg=3, Co=-5
Again, this is the same as saying -5(x^3). Thus, the degree is 3 while the coefficient is -1.
Fourth Term: 7x; Deg=1, Co=7
7x is the same as saying 7x^1. Thus, the degree is 1 while the coefficient is 7.
Fifth Term: x^2; Deg=2, Co=2
x^2 is the same as 1(x^2). Thus, the degree is 2 while the coefficient is 1.
The leading coefficient is the first coefficient when the polynomial is placed in descending order based on degree number. First, arrange the polynomial into descending order based on the degree:
Thus, the leading coefficient is -1 (belonging to the x^4).
The degree of the leading term will always be the highest. In this case, it is 4.
The degree of the polynomial is the highest degree. In this case, it is 4.
