Answer:
y = -1/2(x + 4)² + 2 or y = -1/2x²- 4x - 6
Step-by-step explanation:
Given
Vertex = (-4, 2)
The graph passes through the point (-8, -6)
The function in vertex form is:
y = a(x + 4)² + 2
Substitute the coordinates of (-8, -6) and find the value of a:
-6 = a(-8 + 4)² + 2
-8 = 16a
a = -1/2
The function is:
y = -1/2(x + 4)² + 2
or in standard form:
y = -1/2(x² + 8x + 16) + 2 = -1/2x²- 4x - 6

Answer: 11
<u>Step-by-step explanation:</u>
3x² - 4x¹¹ + 4x⁴ - 2x¹⁰ - 5 + 8x⁸
To find the degree, look for the largest exponent. <em>11</em>
If you put this polynomial in standard form (from largest to smallest exponent), the first term will give you the degree of the polynomial and the leading coefficient.
- 4x¹¹ - 2x¹⁰ + 8x⁸ + 4x⁴ + 3x² - 5
