The vertex of a parabola is at (8,-1)and its y-interpret is-17. Which function represents the parabola
Ilia_Sergeevich [38]

Answer:

D

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

Here (h, k) = (8, - 1), thus

y = a(x - 8)² - 1

To find a substitute (0, - 17), the coordinates of the y- intercept into the equation.

- 17 = a(0 - 8)² - 1

- 17 = 64a - 1 ( add 1 to both sides )

- 16 = 64a ( divide both sides by 64 )

a = \frac{-16}{64} = - \frac{1}{4}

y = - \frac{1}{4}(x - 8)² - 1 → D

Use the factor theorem to determine whether the binomial x + 1 is a factor of the polynomial function ƒ(x) = 2x3 – 9x2 + 13x – 6
Andrews [41]
No, it is not. 
If x+1 is a factor, x=-1 would be one of the zeros. 
Plug x=-1 in the polynomial to see it is results in a 0:
2(-1)^3-9(-1)^2+13(-1)-6=-30≠0, therefore, x+1 is not a factor.
