Answer:

Step-by-step explanation:
Given:
The quadratic function is given as:

The standard form of a quadratic function is given as:
, where, 'a', 'h' and 'k' are real numbers.
Now, in order to convert the given function to standard form, we use completing by square method.
![-x^2+2x=-(x^2-2x)=-[(x-2)^2-2^2]=-[(x-2)^2-4]=-(x-2)^2+4](https://tex.z-dn.net/?f=-x%5E2%2B2x%3D-%28x%5E2-2x%29%3D-%5B%28x-2%29%5E2-2%5E2%5D%3D-%5B%28x-2%29%5E2-4%5D%3D-%28x-2%29%5E2%2B4)
Now,
can be rewritten as:

Therefore, the standard form of the function is:

Answer: 1.37
Step-by-step explanation:
so to find out how far molly walked you have to find out how far her sister and brother walked combined 1.23+0.85=2.08 then subtract 3.45-2.08 to get 1.37
molly waled 1.37 more miles then her brother and sister combined
The second one i got (0,-2) first one i got (0,9)
