We have been given a quadratic function 
and we need to restrict the domain such that it becomes a one to one function.
We know that vertex of this quadratic function occurs at (5,2).
Further, we know that range of this function is 
.
If we restrict the domain of this function to either ![(-\infty,5]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C5%5D)
or 
, it will become one to one function.
Let us know find its inverse.
Upon interchanging x and y, we get:
Let us now solve this function for y.
Hence, the inverse function would be 
if we restrict the domain of original function to and the inverse function would be 
if we restrict the domain to .
Answer:
It is option 1
Step-by-step explanation:
domain is x and the two points range from -1 to 3. The picture quality wasn't that good so if I miss read sry. haha
Number 10 is Answer: y=2.5/2x+3.5
Step-by-step explanation:
The 3.5 is the y intercept because it is when x is 0. The slope is just the change in y over the change in x
