The image contains a set of quadratic functions, and the task is to rewrite each one in standard form and find the vertex.

To convert the quadratic functions into standard form $f(x) = a(x-h)^2 + k$, we will complete the square and identify the vertex $(h, k)$.

I'll start solving these one by one. Let's begin with the first function:

6. $f(x) = x^2 - 12x + 32$

1. The equation is $f(x) = x^2 - 12x + 32$.
2. To complete the square, take half the coefficient of $x$, square it, and add/subtract it inside the equation.
   • Half of $-12$ is $-6$, and $(-6)^2 = 36$.
   • So, rewrite the function as: $f(x) = (x^2 - 12x + 36) - 36 + 32 = (x - 6)^2 - 4$
3. The standard form is $f(x) = (x - 6)^2 - 4$.
4. The vertex is $(h, k) = (6, -4)$.

I'll now continue with the rest.

7. $g(x) = x^2 + 2x - 3$

1. The equation is $g(x) = x^2 + 2x - 3$.
2. Completing the square:
   • Half of 2 is 1, and $(1)^2 = 1$.
   • Rewrite the function: $g(x) = (x^2 + 2x + 1) - 1 - 3 = (x + 1)^2 - 4$
3. The standard form is $g(x) = (x + 1)^2 - 4$.
4. The vertex is $(-1, -4)$.

8. $f(x) = x^2 - x$

1. The equation is $f(x) = x^2 - x$.
2. Completing the square:
   • Half of $-1$ is $-\frac{1}{2}$, and $\left(-\frac{1}{2}\right)^2 = \frac{1}{4}$.
   • Rewrite the function: $f(x) = \left(x^2 - x + \frac{1}{4}\right) - \frac{1}{4} = \left(x - \frac{1}{2}\right)^2 - \frac{1}{4}$
3. The standard form is $f(x) = \left(x - \frac{1}{2}\right)^2 - \frac{1}{4}$.
4. The vertex is $\left(\frac{1}{2}, -\frac{1}{4}\right)$.
