Degree: 5; leading coefficient: 10
Option D is correct.
Step-by-step explanation:
We need to identify if
is a polynomial function, then state its degree and leading coefficient or not.
A polynomial is an algebraic expression containing two or more terms that have same variables but may have different exponents combined through mathematical symbol(+,-,*or/)
So,
is a polynomial function
The degree of polynomial is the highest degree obtained by sum of all exponents of individual terms in the polynomial.
So,
has highest degree 5
Degree = 5
The leading coefficient is the coefficient of first term of the polynomial.
So,
has leading coefficient = 10
So, Leading coefficient = 10
So, Degree: 5; leading coefficient: 10
Option D is correct.

Step-by-step explanation:
Graph C
I am confused what are you asking?
X= -b⁺₋ √b²-4ac/2a
x= (-(-2)⁺₋√(-2)²- 4(4)(-5))/2(4)
x= 4 ⁺₋√4+80/8
x= (4⁺₋ 9.165)/8
x= 4+9.165)/8 or x= 4-9.165)/8
x= 1.40 or x= -0.896
