Todetermine:The given statement is true or false.
Answer to Problem 25E
The given statement is true.
Explanation of Solution
Given information:
Statement: The graph of quadratic model with positive leading coefficient will have a minimum value at its vertex.
Conceptused:
The sign of leading coefficient decides whether graph of quadratic function is opening up or opening down.
When leading coefficient of quadratic function is positive its graph is opening up, and so minimum of the function is at the vertex.
When leading coefficient of quadratic function is negative its graph is opening down, and so maximum of the function is at the vertex.
For example:
The graphs of functions
The graph of function
Hence, the given statement is true.
Conclusion:
The given statement is true.
