Answer: The correct answer is Roy
Answer:
The minimum is -5
The range is 
f(14) = 2739
Step-by-step explanation:
Given

Solving (a): The minimum
A quadratic function is represented as:

If a > 0, then the function has a minimum
By comparison
--- the function has a minimum


To calculate the minimum, we first calculate the following is calculated as:

So, we have:


So, the minimum is at f(m)
We have: 


Solving (b): The range
In (a), we have:
--- the minimum
This implies that the smallest value of y on the graph is -5.
So, the range is:

Solving (c): f(14)
We have:

So:
