Answer:
The degree of the polynomial is 3
Step-by-step explanation:
Given:
![a^3+3a^2-5a](https://tex.z-dn.net/?f=a%5E3%2B3a%5E2-5a)
To Find:
The degree of the polynomial= ?
Solution:
The degree of the polynomial is the value of the greatest exponent of any expression (except the constant ) in the polynomial. To find the degree all that you have to do is find the largest exponent in the polynomial
Here in the given polynomial
![a^3+3a^2- 5a](https://tex.z-dn.net/?f=a%5E3%2B3a%5E2-%205a)
The terms are
![a^3](https://tex.z-dn.net/?f=a%5E3)
![3a^2](https://tex.z-dn.net/?f=3a%5E2)
![5a](https://tex.z-dn.net/?f=5a)
The term
has the largest exponent of 3
Note: The degree of the polynomial does not depend on coefficients of the terms
Answer:I think c
Hope this helped
Answer:
C
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
y = (x + 7)² - 9 ← is in vertex form
with h = - 7 and k = - 9
vertex = (- 7, - 9 )
