Answer:

y=\frac{1}{2}(x+6)^2-1

Step-by-step explanation:

<u>Equation of the Quadratic Function</u>

The vertex form of the quadratic function has the following equation:

y=a(x-h)^2+k

Where (h, k) is the vertex of the parabola that graphically represents the function, and a is a coefficient different from zero.

The vertex of the required equation is located at (-6,-1)

The parabola passes through (-12,17)

Substituting the coordinates of the vertex, the equation of the function is:

y=a(x+6)^2-1

The value of a will be determined by using the given point:

17=a(-12+6)^2-1

Operating:

17=a(36)-1

36a=18\Rightarrow a=18/36=1/2

Solving:

a=1/2

The equation of the parabola is:

\boxed{y=\frac{1}{2}(x+6)^2-1}

umuc stat club must appoint a president. a vice president and a treasurer. There are 8 qualified candidates. How many different
zalisa [80]
The best possible solution for this item is to determine the permutation of 8 taken 3 since there are 3 positions and 8 people are qualified. We will use permutation instead of combination because of the specificity of the positions. That is,
                                 8P3 = 336
Thus, there are 336 ways in which the officers can be selected.
