It looks like you’ve uploaded a page with quadratic functions, and you need help identifying key features for the problems.

I can help break down each function, identifying the vertex, x-intercepts, and y-intercepts, as well as converting them into different forms.

Let's start with problem 17:

The function is: $f(x) = \frac{1}{2}(x + 6)(x + 2)$

Steps to Find the Key Features:

1. Vertex: To find the vertex, we first expand the equation into standard form or use the midpoint formula for the roots (since this is a factored form).
2. x-intercepts: These occur where $f(x) = 0$, or when each factor is equal to zero.
3. y-intercept: This is where $x = 0$, so we substitute $x = 0$ into the function.

Would you like me to continue solving this problem in detail, or would you prefer I move on to the next one?
