Answer:
Honestly um I started a few days ago yet dont know
Step-by-step explanation:
f(x) = |x-7| + 3
when x is equal to 4, then
f(4) = |4-7| + 3
=-3+3
=0
Answer:

Step-by-step explanation:
We are given the following;
- Vertex of a quadratic function = (5,3)
- A point where the function passes through (-1, -9)
Required to determine the equation of the function;
- We need to know the vertex form of a quadratic function is;
, where h and k correspond to the vertex (h,k)
- Therefore, we can replace the variables h and k of the vertex in the equation;
That is;

Then we use the equation and the point given to solve for a
x = -1 and y = -9
We get;

Substituting the values of a, h and k in the equation, we get;

Thus, the equation of the function in the vertex form is 
The answer would be D because you are subtracting a positive 17 from a positive 88
