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:
